Adapt idea.c to the Libgcrypt framework. Add IDEA to cipher_table and to the build system. Patents on IDEA have expired: Europe: EP0482154 on 2011-05-16, Japan: JP3225440 on 2011-05-16, U.S.: 5,214,703 on 2012-01-07. * configure.ac: Add idea to the list of available ciphers. Define USE_IDEA if idea is enabled. * cipher/cipher.c (cipher_table): Add entry for IDEA. * cipher/idea.c: Update comment about patents. Include proper header files and remove redundant declarations. (expand_key, cipher, do_setkey, encrypt_block, decrypt_block): Define function arguments as const where appropriate. (cipher): Test for !WORDS_BIGENDIAN instead of LITTLE_ENDIAN_HOST. (do_setkey, decrypt_block): Don't call selftest. (idea_setkey): New function, wrapper for do_setkey. (idea_encrypt): New function, wrapper for encrypt_block. (_gcry_cipher_spec_idea): Define. * cipher/Makefile.am (EXTRA_libcipher_la_SOURCES): Add idea.c. * src/cipher.h (_gcry_cipher_spec_idea): Declare. * tests/basic.c (check_ciphers): Add GCRY_CIPHER_IDEA. --- src/cipher.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/cipher.h') diff --git a/src/cipher.h b/src/cipher.h index 0f923d79..48eeeda5 100644 --- a/src/cipher.h +++ b/src/cipher.h @@ -135,6 +135,7 @@ extern gcry_cipher_spec_t _gcry_cipher_spec_seed; extern gcry_cipher_spec_t _gcry_cipher_spec_camellia128; extern gcry_cipher_spec_t _gcry_cipher_spec_camellia192; extern gcry_cipher_spec_t _gcry_cipher_spec_camellia256; +extern gcry_cipher_spec_t _gcry_cipher_spec_idea; extern cipher_extra_spec_t _gcry_cipher_extraspec_tripledes; extern cipher_extra_spec_t _gcry_cipher_extraspec_aes; -- cgit v1.2.1
