klyn.cryptography.Signature.verify
method
public verify(signature as String, text as String = null, inputEncoding as String = "base64") as Boolean throws CryptoException:
Description
Verifies a signature against the buffered text and an optional final chunk. 
import klyn.cryptography

keys = RSAKeyPairGenerator().generateKeyPair()
signer = RSAPSSSignature(SHA256())
signer.initSign(keys.privateKeyPem)
token = signer.sign("hello")
verifier = RSAPSSSignature(SHA256())
verifier.initVerify(keys.publicKeyPem)
print(verifier.verify(token, "hello"))
Parameters
  • signature Encoded signature value.
  • text Optional final UTF-8 chunk.
  • inputEncoding Signature encoding: `base64`, `base64url` or `hex`.
Returns
True when the signature is valid.
Throws
  • CryptoException when the instance is not initialized for verification. ```klyn import klyn.cryptography keys = RSAKeyPairGenerator().generateKeyPair() signer = RSAPSSSignature(SHA256()) signer.initSign(keys.privateKeyPem) token = signer.sign("hello") verifier = RSAPSSSignature(SHA256()) verifier.initVerify(keys.publicKeyPem) print(verifier.verify(token, "hello")) ```
