Re: [Pharo-users] SHA256 hashing with secret key..

I havent checked the Facebook API but don't you simply need to concatenate your key with the text you need to hash ? SHA256 hashMessage: ('test' , 'APIKey') hex ? On 30/09/12 15:00, sergio_101 wrote:

hey, all...

i installed the Cryptography library, and can produce a has like:

SHA256 hashMessage: 'test' hex.

the problem i am running into is, i need to generate the SHA256 with my AppKey from facebook. i can't figure out how to generate a hash using a secret key.

i tried looking through the source code, but couldn't find anything for SHA256..

any ideas?

thanks!
