klyn.cryptography.Cipher.aesDecrypt
method
public static aesDecrypt(payload as AESCipherText, key as String, keyEncoding as String = "base64", aad as String = null) as String throws CryptoException:
Description
Decrypts an AES payload produced by `aesEncrypt`. 
import klyn.cryptography

key = AESKeyGenerator().generateKey()
payload = Cipher.aesEncrypt("hello", key)
print(Cipher.aesDecrypt(payload, key))
Parameters
  • payload Structured AES payload.
  • key AES key material.
  • keyEncoding Key encoding: `base64`, `base64url`, `hex` or `utf8`.
  • aad Optional additional authenticated data for `GCM`.
Returns
Decrypted UTF-8 text.
Throws
  • CryptoException when authentication or decryption fails. ```klyn import klyn.cryptography key = AESKeyGenerator().generateKey() payload = Cipher.aesEncrypt("hello", key) print(Cipher.aesDecrypt(payload, key)) ```
