1 Noteworthy changes in version 1.1.43 (unreleased)
2 -------------------------------------------------
4 * Bug fixes and internal code cleanups
6 * Support for the Serpent cipher algorithm.
8 * Interface changes relative to the 1.1.42 release:
9 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10 gcry_prime_generate NEW
14 Noteworthy changes in version 1.1.42 (2003-07-31)
15 -------------------------------------------------
17 * Major API cleanup. Applications need to be converted to the new
18 API. See README.apichanges for hints on how to do that. Backward
19 compatibility is provided where it was possible without too much
20 effort and did not collide with the overall sanitization effort.
21 However, this is only for ease of transition. NO DEPRECATED
22 FUNCTION OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND
23 WILL BE DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE
26 * If gcrypt.h is included in sources compiled by GCC 3.1 or later,
27 deprecated attributes will warn about use of obsolete functions and
28 type definitions. You can suppress these warnings by passing
29 -Wno-deprecated-declarations to the gcc command.
31 * gcry_check_version must be called from now on to initialize the
32 library, it is not longer optional.
34 * Removed `libgcrypt errno' concept.
36 * Libgcrypt depends on libgpg-error, a library that provides error
37 codes and according functions for all GnuPG components. Functions
38 that used to return error codes asa `int' have been changed to
39 return a code of type `gcry_error_t'. All GCRYERR_* error symbols
40 have been removed, since they are now contained in libgpg-error
41 (GPG_ERR_*). All functions and types in libgpg-error have also been
42 wrapped in Libgcrypt. The new types are gcry_err_code_t and
43 gcry_err_source_t. The new functions are gcry_err_code,
44 gcry_err_source, gcry_error, gcry_err_make, gcry_error_from_errno,
45 gcry_err_make_from_errno, gcry_err_code_from_errno,
46 gcry_err_code_to_errno, gcry_strsource.
48 * New function gcry_mpi_dump to help in debugging.
50 * Added alternative interface for asymmetric cryptography.
52 * CRC-32, CRC-32 a'la RFC 1510, CRC-24 a'la RFC 2440 are now
55 * SHA-256, SHA-384 and SHA-512 are now supported.
57 * 128 bit Twofish is now supported.
59 * The random module won't print the "not enough random bytes
60 available" anymore. A new progress status is issued instead.
62 * CBC-MAC for block ciphers is now supported, by using a
63 GCRY_CIPHER_CBC_MAC cipher flag.
65 * CTR mode for block ciphers is now supported.
67 * The public RSA exponent can now be specified in key generation.
69 * RSA blinding is now supported and is used automatically for RSA
70 decryption. It can be explicitely disabled by using the
71 `no-blinding' symbol in the `flags' S-Expression or by using the
72 GCRY_AC_FLAG_DATA_NO_BLINDING flag when using the ac interface.
74 * gcry_sexp_canon_len does not use a `historically encoded' error
