Generate s3 signature with no access to aws cli
Really hitting a wall with this one so be great to get a bit of guidance. Basically I have a client who uses sas 9.3 and has no s3 connector or aws cli but I need to connect to s3 so the only way I can do it is useing grroovy and the java libraries however I can't get this to work. Everytime I try do this I get a
The request signature we calculated does not match the signature you provided. Check your key and signing method
error message. I was wondering has anyone exp with this or could someone please help me on this as I can't get it to work. Thanks very much in advance.
Code:
proc groovy;
add sasjar="commons_codec" ;
submit "&s3secret." "&stringToSign.";
import javax.crypto.Mac
import javax.crypto.spec.SecretKeySpec
import org.apache.commons.codec.binary.Base64
def base64hmacsha256(key, message) {
mac = Mac.getInstance("HmacSHA256")
mac.init(new SecretKeySpec(key.getBytes(), "HmacSHA256"))
sha1_bytes = mac.doFinal(message.getBytes())
base64 = new Base64()
return mac.doFinal(message.getBytes("UTF8"));
}
exports.base64hmacsha256 = base64hmacsha256(args[0], args[1])
endsubmit;
quit;

You have not shown all of your relevant code. If your string to sign you generate is wrong, then your signature will also necessarily be wrong.
