Noteworthy changes in version 1.4.5 (2009-12-11) ------------------------------------------------ * Fixed minor memory leak in DSA key generation. * No more switching to FIPS mode if /proc/version is not readable. * Fixed a sigill during Padlock detection on old CPUs. * Fixed a hang on some W2000 machines. * Boosted SHA-512 performance by 30% on ia32 boxes and gcc 4.3; SHA-256 went up by 25%. Noteworthy changes in version 1.4.4 (2009-01-22) ------------------------------------------------ * Publish GCRY_MODULE_ID_USER and GCRY_MODULE_ID_USER_LAST constants. This functionality has been in Libgcrypt since 1.3.0. * MD5 may now be used in non-enforced fips mode. * Fixed HMAC for SHA-384 and SHA-512 with keys longer than 64 bytes. * In fips mode, RSA keys are now generated using the X9.31 algorithm and DSA keys using the FIPS 186-2 algorithm. * The transient-key flag is now also supported for DSA key generation. DSA domain parameters may be given as well. Noteworthy changes in version 1.4.3 (2008-09-18) ------------------------------------------------ * Try to auto-initialize Libgcrypt to minimize the effect of applications not doing that correctly. This is not a perfect solution but given that many applicationion would totally fail without such a hack, we try to help at least with the most common cases. Folks, please read the manual to learn how to properly initialize Libgcrypt! * Auto-initialize the secure memory to 32k instead of aborting the process. * Log fatal errors via syslog. * Changed the name and the semantics of the fips mode config file. * Add convenience macro gcry_fips_mode_active. * More self-tests. * Documentation cleanups. Noteworthy changes in version 1.4.2 (2008-09-08) ------------------------------------------------ * The long missing gcry_mpi_lshift function has been added. * RSA key generation now supports a "transient-key" flag. * The keygrip computation for ECDSA has been implemented thus ECDSA is now fully supported. * A few macros have been replaced by functions for better type checking. * The thread initialization structure now carries version information. * The manual describes more clearly how to initialize Libgcrypt. * The library may now be switched into a FIPS mode. * Interface changes relative to the 1.3.0 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GCRYCTL_OPERATIONAL_P NEW. GCRYCTL_FIPS_MODE_P NEW. GCRYCTL_FORCE_FIPS_MODE NEW. gcry_cipher_setkey NEW: Replaces macro. gcry_cipher_setiv NEW: Replaces macro. gcry_cipher_setctr NEW: Replaces macro. gcry_mpi_lshift NEW. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 1.4.1 (2008-04-25) ------------------------------------------------ * Fixed a bug introduced by 1.3.1 which led to the comsumption of far too much entropy for the intial seeding. * Improved AES performance for CFB and CBC modes. * Removed build problems for the Padlock support. Noteworthy changes in version 1.4.0 (2007-12-10) ------------------------------------------------ * New configure option --disable-padlock-support which is mostly useful in case of build problems. Noteworthy changes in version 1.3.2 (2007-12-03) ------------------------------------------------ * The visibility attribute is now used if supported by the toolchain. * The ACE engine of VIA processors is now used for AES-128. * The ASN.1 DER template for SHA-224 has been fixed. Noteworthy changes in version 1.3.1 (2007-10-26) ------------------------------------------------ * The entire library is now under the LGPL. The helper programs and the manual are under the GPL. Kudos to Peter Gutmann for giving permissions to relicense the rndw32 and rndunix modules. * The Camellia cipher is now under the LGPL and included by default. * Fixed a bug in the detection of symbol prefixes which inhibited the build of optimzied assembler code on certain systems. * Updated the entropy gatherer for W32. Noteworthy changes in version 1.3.0 (2007-05-04) ------------------------------------------------ * Changed the way the RNG gets initialized. This allows to keep it uninitialized as long as no random numbers are used. To override this, the new macro gcry_fast_random_poll may be used. It is in general a good idea to spread this macro into the application code to make sure that these polls happen often enough. * Made the RNG immune against fork without exec. * Reading and writing the random seed file is now protected by a fcntl style file lock on systems that provide this function. * Support for SHA-224 and HMAC using SHA-384 and SHA-512. * Support for the SEED cipher. * Support for the Camellia cipher. Note that Camellia is disabled by default, and that enabling it changes the license of libgcrypt from LGPL to GPL. * Support for OFB encryption mode. * gcry_mpi_rshift does not anymore truncate the shift count. * Reserved algorithm ranges for use by applications. * Support for DSA2. * The new function gcry_md_debug should be used instead of the gcry_md_start_debug and gcry_md_stop_debug macros. * New configure option --enable-random-daemon to support a system wide random daemon. The daemon code is experimental and not yet very well working. It will eventually allow to keep a global random pool for the sake of short living processes. * Non executable stack support is now used by default on systems supporting it. * Support for Microsoft Windows. * Assembler support for the AMD64 architecture. * New configure option --enable-mpi-path for optimized builds. * Experimental support for ECDSA; should only be used for testing. * New control code GCRYCTL_PRINT_CONFIG to print the build configuration. * Minor changes to some function declarations. Buffer arguments are now typed as void pointer. This should not affect any compilation. Fixed two bugs in return values and clarified documentation. * Interface changes relative to the 1.2.0 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcry_fast_random_poll NEW gcry_md_debug NEW gcry_sexp_nth_string NEW GCRY_MD_SHA224 NEW GCRY_PK_USAGE_CERT NEW GCRY_PK_USAGE_AUTH NEW GCRY_PK_USAGE_UNKN NEW GCRY_PK_ECDSA NEW GCRY_CIPHER_SEED NEW GCRY_CIPHER_CAMELLIA128 NEW GCRY_CIPHER_CAMELLIA192 NEW GCRY_CIPHER_CAMELLIA256 NEW GCRYCTL_FAKED_RANDOM_P NEW GCRYCTL_PRINT_CONFIG NEW GCRYCTL_SET_RNDEGD_SOCKET NEW. gcry_mpi_scan CHANGED: Argument BUFFER is now void*. gcry_pk_algo_name CHANGED: Returns "?" instead of NULL. gcry_cipher_algo_name CHANGED: Returns "?" instead of "". gcry_pk_spec_t CHANGED: Element ALIASES is now const ptr. gcry_md_write_t CHANGED: Argument BUF is now a const void*. gcry_md_ctl CHANGED: Argument BUFFER is now void*. gcry_cipher_encrypt CHANGED: Arguments IN and OUT are now void*. gcry_cipher_decrypt CHANGED: Arguments IN and OUT are now void*. gcry_sexp_sprint CHANGED: Argument BUFFER is now void*. gcry_create_nonce CHANGED: Argument BUFFER is now void*. gcry_randomize CHANGED: Argument BUFFER is now void*. gcry_cipher_register CHANGED: Argument ALGORITHM_ID is now int*. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 1.2.0 (2004-04-15) ------------------------------------------------ * First stable release. Noteworthy changes in version 1.1.94 (2004-03-29) ------------------------------------------------- * The support for multi-threaded users goes into its third incarnation. We removed compile time support for thread libraries. To support the thread library of your choice, you have to set up callback handlers at initialization time. New data structures, a new control command, and default initializers are provided for this purpose. * Interface changes relative to the 1.1.93 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ libgcrypt-config --thread OBSOLETE libgcrypt-pth.la REMOVED libgcrypt-pthread.la REMOVED GCRYCTL_SET_THREAD_CBS NEW struct gcrypt_thread_cbs NEW enum gcry_thread_option NEW GCRY_THREAD_OPTION_PTH_IMPL NEW GCRY_THREAD_OPTION_PTHREAD_IMPL NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 1.1.93 (2004-03-06) ------------------------------------------------- * The automatic thread library detection has finally been removed. From now on, only linking explicitely to libgcrypt, libgcrypt-pth or libgcrypt-pthread is supported. Noteworthy changes in version 1.1.92 (2004-02-20) ------------------------------------------------- * Minor bug fixes. * Included a limited implementation of RFC2268. * Changed API of the gcry_ac_ functions. Only a very few programs should be affected by this. * Interface changes relative to the 1.1.91 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GCRY_CIPHER_RFC2268_40 NEW. gcry_ac_data_set CHANGED: New argument FLAGS. gcry_ac_data_get_name CHANGED: New argument FLAGS. gcry_ac_data_get_index CHANGED: New argument FLAGS. gcry_ac_key_pair_generate CHANGED: New and reordered arguments. gcry_ac_key_test CHANGED: New argument HANDLE. gcry_ac_key_get_nbits CHANGED: New argument HANDLE. gcry_ac_key_get_grip CHANGED: New argument HANDLE. gcry_ac_data_search REMOVED. gcry_ac_data_add REMOVED. GCRY_AC_DATA_FLAG_NO_BLINDING REMOVED. GCRY_AC_FLAG_NO_BLINDING NEW: Replaces above. Noteworthy changes in version 1.1.91 (2003-12-19) ------------------------------------------------- * Code cleanups and minor bug fixes. Noteworthy changes in version 1.1.90 (2003-11-14) ------------------------------------------------- * The use of the GCRY_WEAK_RANDOM level is now deprecated in favor of the new gcry_create_nonce function. * gcry_sexp_build now supports a "%b" format to include a memory buffer. * Minor configuration fixes. * Interface changes relative to the 1.1.44 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcry_create_nonce NEW gcry_sexp_build ENHANCED Noteworthy changes in version 1.1.44 (2003-10-31) ------------------------------------------------- * Bug fixes and more code cleanups. * Enhanced the prime API. * Interface changes relative to the 1.1.43 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcry_prime_group_generator NEW gcry_prime_release_factors NEW Noteworthy changes in version 1.1.43 (2003-09-04) ------------------------------------------------- * Bug fixes and internal code cleanups. * Support for the Serpent cipher algorithm. * Interface changes relative to the 1.1.42 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcry_prime_generate NEW gcry_prime_check NEW Noteworthy changes in version 1.1.42 (2003-07-31) ------------------------------------------------- * Major API cleanup. Applications need to be converted to the new API. See README.apichanges for hints on how to do that. Backward compatibility is provided where it was possible without too much effort and did not collide with the overall sanitization effort. However, this is only for ease of transition. NO DEPRECATED FUNCTION OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND WILL BE DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE LIBRARY. * If gcrypt.h is included in sources compiled by GCC 3.1 or later, deprecated attributes will warn about use of obsolete functions and type definitions. You can suppress these warnings by passing -Wno-deprecated-declarations to the gcc command. * gcry_check_version must be called from now on to initialize the library, it is not longer optional. * Removed `libgcrypt errno' concept. * Libgcrypt depends on libgpg-error, a library that provides error codes and according functions for all GnuPG components. Functions that used to return error codes asa `int' have been changed to return a code of type `gcry_error_t'. All GCRYERR_* error symbols have been removed, since they are now contained in libgpg-error (GPG_ERR_*). All functions and types in libgpg-error have also been wrapped in Libgcrypt. The new types are gcry_err_code_t and gcry_err_source_t. The new functions are gcry_err_code, gcry_err_source, gcry_error, gcry_err_make, gcry_error_from_errno, gcry_err_make_from_errno, gcry_err_code_from_errno, gcry_err_code_to_errno, gcry_strsource. * New function gcry_mpi_dump to help in debugging. * Added alternative interface for asymmetric cryptography. * CRC-32, CRC-32 a'la RFC 1510, CRC-24 a'la RFC 2440 are now supported. * SHA-256, SHA-384 and SHA-512 are now supported. * 128 bit Twofish is now supported. * The random module won't print the "not enough random bytes available" anymore. A new progress status is issued instead. * CBC-MAC for block ciphers is now supported, by using a GCRY_CIPHER_CBC_MAC cipher flag. * CTR mode for block ciphers is now supported. * The public RSA exponent can now be specified in key generation. * RSA blinding is now supported and is used automatically for RSA decryption. It can be explicitely disabled by using the `no-blinding' symbol in the `flags' S-Expression or by using the GCRY_AC_FLAG_DATA_NO_BLINDING flag when using the ac interface. * gcry_sexp_canon_len does not use a `historically encoded' error code anymore. * Interface changes relative to the 1.1.12 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GCRY_MPI DEPRECATED; Use: gcry_mpi_t GcryMPI DEPRECATED; Use: gcry_mpi_t GCRY_SEXP DEPRECATED; Use: gcry_sexp_t GcrySexp DEPRECATED; Use: gcry_sexp_t GCRY_CIPHER_HD DEPRECATED; Use: gcry_cipher_hd_t GcryCipherHd DEPRECATED; Use: gcry_cipher_hd_t GCRY_MD_HD DEPRECATED; Use: gcry_md_hd_t GcryMDHd DEPRECATED; Use: gcry_md_hd_t gcry_error_t NEW gcry_err_code_t NEW gcry_err_source_t NEW gcry_err_make NEW gcry_error NEW gcry_err_code NEW gcry_err_source NEW gcry_err_code_from_errno NEW gcry_err_code_to_errno NEW gcry_err_make_from_errno NEW gcry_error_from_errno NEW gcry_strsource NEW GCRYERR_{some error code} REMOVED; Use GPG_ERR_* from libgpg-error instead. gcry_errno REMOVED gcry_sexp_canon_len CHANGED gcry_sexp_build_array NEW gcry_mpi_scan CHANGED: New argument to separate in/out args. gcry_mpi_print CHANGED: Ditto. gcry_mpi_dump NEW gcry_cipher_open CHANGED gcry_cipher_reset NEW gcry_cipher_register NEW gcry_cipher_unregister NEW gcry_cipher_list NEW gcry_cipher_algo_keylen REPLACED macro with function. gcry_cipher_algo_blklen REPLACED macro with function. gcry_pk_register NEW gcry_pk_unregister NEW gcry_pk_list NEW gcry_pk_decrypt ENHANCED: Allows flag to return complete S-expression. gcry_md_open CHANGED gcry_md_copy CHANGED gcry_md_is_enabled NEW gcry_md_is_secure NEW gcry_md_register NEW gcry_md_unregister NEW gcry_md_list NEW gcry_ac_data_t NEW gcry_ac_key_t NEW gcry_ac_key_pair_t NEW gcry_ac_handle_t NEW gcry_ac_key_spec_rsa_t NEW gcry_ac_data_new NEW gcry_ac_data_destroy NEW gcry_ac_data_set NEW gcry_ac_data_copy NEW gcry_ac_data_length NEW gcry_ac_data_get_name NEW gcry_ac_data_get_index NEW gcry_ac_data_clear NEW gcry_ac_open NEW gcry_ac_close NEW gcry_ac_key_init NEW gcry_ac_key_pair_generate NEW gcry_ac_key_pair_extract NEW gcry_ac_key_data_get NEW gcry_ac_key_test NEW gcry_ac_key_get_nbits NEW gcry_ac_key_get_grip NEW gcry_ac_key_destroy NEW gcry_ac_key_pair_destroy NEW gcry_ac_data_encrypt NEW gcry_ac_data_decrypt NEW gcry_ac_data_sign NEW gcry_ac_data_verify NEW gcry_ac_id_to_name NEW gcry_ac_name_to_id NEW gcry_handler_progress_t NEW gcry_handler_alloc_t NEW gcry_handler_secure_check_t NEW gcry_handle_realloc_t NEW gcry_handler_free_t NEW gcry_handler_no_mem_t NEW gcry_handler_error_t NEW gcry_handler_log_t NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 1.1.12 (2003-01-20) ------------------------------------------------- * gcry_pk_sign, gcry_pk_verify and gcry_pk_encrypt can now handle an optional pkcs1 flags parameter in the S-expression. A similar flag may be passed to gcry_pk_decrypt but it is only syntactically implemented. * New convenience macro gcry_md_get_asnoid. * There is now some real stuff in the manual. Noteworthy changes in version 1.1.11 (2002-12-21) ------------------------------------------------- * Don't export internal symbols anymore (currently only for GNU systems) * New algorithm: MD4 * Implemented ciphertext stealing. * Smaller bugs fixes and a few new OIDs. * Interface changes relative to the 1.1.8 release: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcry_cipher_cts NEW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Noteworthy changes in version 1.1.10 (2002-09-20) ------------------------------------------------- * Fixed shared library builds for i386, PPC and Sparc. * Added simple benchmark tool. * Replaced the internal mutexes by code which automatically adapts to the used threading library.
