* Restructure the crypto checksum implementation to minimizeGreg Hudson2009-12-1044-1278/+858
| | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | 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
