An other alternative is using the CommonCrypto API (which does not require to link on other library like OpenSSL).

man "Common Crypto"

I ran into a similar problem - but I decided to use libcrypto:
man 3 sha1
or
man 3 EVP_DigestInit

Hi

I wrote a SHA class using the algorithm at
http://en.wikipedia.org/wiki/SHA1#SHA-1_pseudocode and while it runs
without crashing, the hashes it produces are not the same as those from numerous online SHA-1 hashing converters. Of particular confusion is the issue of byte swapping and how that might affect the rotation/ addition operations within the block hashing method. I'm clearly doing something wrong, but after several days of trying, I haven't been able to get the
hashes to match online examples.

Could someone with knowledge of SHA take a look at the class and point out
where I'm messing up?

Any help appreciated.
