* Makefile.in (hogweed_SOURCES): Added dsa-sha1-sign.c,
dsa-sha1-verify.c, dsa-sha256-sign.c, and dsa-sha256-verify.c. * dsa.h: Updated and added dsa declarations. * dsa-sha256-verify.c (dsa_sha256_verify_digest): New file, new function. (dsa_sha256_verify): New function. * dsa-sha256-sign.c (dsa_sha256_sign_digest): New file, new function. (dsa_sha256_sign): New function. * dsa-sha1-verify.c (dsa_sha1_verify_digest): New file. Moved and renamed function, from dsa_verify_digest, rewrote to use _dsa_verify. (dsa_sha1_verify): Analogous change, renamed from dsa_verify. * dsa-sha1-sign.c (dsa_sha1_sign_digest): New file. Moved and renamed function, from dsa_sign_digest, rewrote to use _dsa_sign, and added return value. (dsa_sha1_sign): Analogous change, renamed from dsa_sign. * dsa-verify.c (_dsa_verify): New general verification function, for any hash. * dsa-sign.c (_dsa_sign): New general signing function, for any hash. Returns success code, like the rsa signture functions.
