A reliable js sha1 implementation

[Paolo]

Hi
I am looking for a javascript stable and secure sha-1 and sha-2
implementation.
I found some versions of different authors but I am unable to know if they
are RELIABLE

Please, can you help me?
Thank you in advance

http://www.movable-type.co.uk/scripts/sha1.html looks like a well-
thought solution from a guy with a lot of expertise in this field.
