Hi,

I'm reading this:

http://www.openssl.org/docs/crypto/sha.html

"[...]
DESCRIPTION

SHA-1 (Secure Hash Algorithm) is a cryptographic hash function with a
160 bit output.

SHA1() computes the SHA-1 message digest of the n bytes at d and
places it in md (which must have space for SHA_DIGEST_LENGTH == 20
bytes of output). If md is NULL, the digest is placed in a static
array.
[...]"

And I wanted to use sha1sum from my linux command line:

"[...]
DESCRIPTION
       Print or check SHA1 (160-bit) checksums.
[...]"

are thes equivalent to each others? or should I use the openssl
toolkit? I ask this cause sha1sum results are 41 bytes long. the
SHA-1() doc says 20bytes for output.

Regards,

If you want freedom, compile the source. Get gentoo.
