klyn.cryptography.Cipher.aesGcmDecrypt
method
public static aesGcmDecrypt(payload as AESCipherText, key as String, keyEncoding as String = "base64", aad as String = null) as String throws CryptoException:
Description
Convenience AES-GCM decryption helper. 
import klyn.cryptography

key = AESKeyGenerator().generateKey()
payload = Cipher.aesGcmEncrypt("hello", key)
print(Cipher.aesGcmDecrypt(payload, key))
Parameters
  • payload Structured AES-GCM payload.
  • key AES key material.
  • keyEncoding Key encoding. Defaults to `base64`.
  • aad Optional additional authenticated data.
Returns
Decrypted UTF-8 text.
Throws
  • CryptoException on authentication or decryption failure. ```klyn import klyn.cryptography key = AESKeyGenerator().generateKey() payload = Cipher.aesGcmEncrypt("hello", key) print(Cipher.aesGcmDecrypt(payload, key)) ```
