Remove support for SHA0 and DSS0 (they were broken), and remove the ability to attempt to build without SHA (it didn't work). For simplicity, remove the option of not building various SHA algorithms; you could argue that SHA_224/256/384/512 should be kept, since they're like crypto algorithms, but I decided to go the other way. So these options are gone: GENUINE_DSA OPENSSL_NO_SHA0 OPENSSL_NO_SHA OPENSSL_NO_SHA1 OPENSSL_NO_SHA224 OPENSSL_NO_SHA256 OPENSSL_NO_SHA384 OPENSSL_NO_SHA512 Reviewed-by: Richard Levitte <levitte@openssl.org>
