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.
