req := 'Service=AWSECommerceService&AWSAccessKeyId=mykey&Operation=ItemLookup&ItemId=3952334146&Timestamp=', DateAndTime now printString. sign :=SHA256 hashMessage: 'GET', String crlf, ' ecs.amazonaws.com', String crlf, '/onca/xml',String crlf,req.
Wenn did you do the encodeForHTTP? You need it in any case because at least the + sign is an encoded space that will render the date invalid. I think you need do safe url encoding only for the string if it is included in the url not the hash.
Yes, but then Amazon answers a signature not valid error. Indeed it seems I need to pass a secret key (given by Amazon) for SHA256 hash, but I don't find how to pass it to a SHA256 object.
In PHP I would write: base64_encode(hash_mac('sha256', $signature, $secret_key)).
In Pharo ?
