Syntax

verifyString(
   key xml.CryptoKey,
   signedStr STRING,
   signature STRING )
  RETURNING flag INTEGER

key is the key to use for verification.
signedStr is the signed string in its clear form.
signature is the signature to be verified.

Usage

The key can be a HMAC key, a RSA private key or a DSA private key. The HMAC key must be the same as the one used for signing. The public RSA and DSA key must be the public key corresponding to the private key used for signing.
