* Improves prng code modularity. Introduces fortuna-like prng that can be used ↵Zhanna Tsitkov2010-10-0516-2188/+0
| | | | | | | | | in lieu of yarrow. Yarrow stays the default prng while fortuna may be engaged during configuration by using "--with-prng-alg=fortuna" flag. Also, nss crypto backend continues to use its own prng. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24420 dc483132-0cff-0310-8789-dd5450dbe970

* yarrow code does not initialize keyblock enctype and uses unitialized valueEzra Peisach2010-01-082-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The yarrow code uses a keyblock that is partially initialized. This results in krb5_k_free_key trying to look up the enctype to call the free handler. One of the valgrind reports: (there are several paths) ==26701== Conditional jump or move depends on uninitialised value(s) ==26701== at 0x40E9AF0: find_enctype (etypes.h:81) ==26701== by 0x40E9C9E: krb5_k_free_key (key.c:91) ==26701== by 0x40D641A: krb5int_yarrow_cipher_init (ycipher.c:49) ==26701== by 0x40D593A: yarrow_gate_locked (yarrow.c:578) ==26701== by 0x40D5349: krb5int_yarrow_output_Block (yarrow.c:423) ==26701== by 0x40D581B: yarrow_output_locked (yarrow.c:553) ==26701== by 0x40D5667: krb5int_yarrow_output (yarrow.c:513) ==26701== by 0x40EBD2D: krb5_c_random_make_octets (prng.c:112) ==26701== by 0x40D4119: krb5int_old_encrypt (old_aead.c:97) ==26701== by 0x40E9696: krb5_k_encrypt_iov (encrypt_iov.c:42) ==26701== by 0x8049554: main (t_encrypt.c:206) ==26701== ticket: 6625 tags: pullup git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23609 dc483132-0cff-0310-8789-dd5450dbe970
* Consolidate the IOV and non-IOV encryption/decryption code paths, andGreg Hudson2009-12-041-18/+12
| | | | | | | | | | | | | | | | | | | | | | | | drop the _iov suffix from most encryption- and decryption-related functions. The enc_provider encrypt and decrypt functions take IOVs, as do the enctype entries in etypes.c, and there are no separate encrypt_iov or decrypt_iov functions. aead_provider is gone. Enctype functions now take pointers to the enctype entry instead of pointers to the enc/hash/aead providers; this allows dk_encrypt and dk_decrypt to be polymorphic in the length function they use now that AES and DES3 can't differentiate by aead provider. aes_string_to_key needed to be moved into the krb/ fold for this since it's an enctype function; it was duplicated between builtin/ and openssl/ before. This leaves openssl/aes empty; the build system currently demands that all modules have the same directory structure, so the directory and Makefile will stick around for now. Three separate copies of the derive_random logic are also now consolidated into one. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23444 dc483132-0cff-0310-8789-dd5450dbe970
