klyn.cryptography.Signature.sign
method
public sign(text as String = null, outputEncoding as String = "base64") as String throws CryptoException:
Description
Signs the buffered text and an optional final chunk. 
import klyn.cryptography

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