SHA1 hashes not matching between my Rails and Cocoa apps

ruby-on-rails objective-c ruby cocoa sha1

Found the error, stupid little thing:

-CC_SHA1([self bytes], CC_SHA1_DIGEST_LENGTH, hashBytes);+CC_SHA1([self bytes], [self length], hashBytes);

I sent the length of the digest instead of the length of the data. Don't know how I could've made such a mistake – and then overlook it for hours.
