2009-12-10Restructure the crypto checksum implementation to minimizeGreg Hudson2-0/+53
dependencies on the internals of modules. * Keyhash providers are gone. * The cksumtypes table contains checksum and verify functions, similar to the etypes encrypt and decrypt functions. New checksum functions parallel the old keyhash providers, and there are also functions for unkeyed and derived-key HMAC checksums. * The flags field is now used to indicate whether a checksum is unkeyed, but not whether it is a derived-key HMAC checksum. * The descbc checksum is handled through a new enc_provider function which calculates a CBC MAC. The OpenSSL module does not implement the CBC MAC function (it didn't implement descbc before). builtin/des could probably get rid of f_cksum.c (the old DES CBC routine) with some alterations to string2key.c. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23462 dc483132-0cff-0310-8789-dd5450dbe970
2009-12-04Consolidate the IOV and non-IOV encryption/decryption code paths, andGreg Hudson7-408/+112
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
2009-12-02Speed up the per-block loops of AES, DES3, and DES IOV encryption byGreg Hudson2-180/+94
avoiding function calls and copies in the case where the next block is wholly contained within the current buffer. To do this, introduce two new inline functions in aead.h called iov_next_block and iov_store_block. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23430 dc483132-0cff-0310-8789-dd5450dbe970
2009-11-30Fix ivec chaining for DES iov encryptionGreg Hudson1-2/+5
krb5int_des_cbc_decrypt_iov was using a plaintext block to update the ivec. Fix it to use the last cipher block, borrowing from the corresponding des3 function. The impact of this bug is not serious since ivec chaining is not typically used with IOV encryption in 1.7. ticket: 6588 tags: pullup target_version: 1.7.1 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23389 dc483132-0cff-0310-8789-dd5450dbe970
