fun createEncryptCipher(): Cipher (source)
Create a cipher initialized for encrypting data with the managed key.
This "low-level" method is useful when a cryptographic context is needed to integrate with
other APIs, such as the FingerprintManager.
NOTE: The caller is responsible for associating certain encryption factors, such as the initialization vector and/or additional authentication data (AAD), with the resulting ciphertext or decryption will fail.
InvalidKeyException - If the key does not exist, or is not a SecretKey
NoSuchAlgorithmException - If the cipher algorithm is not supported
NoSuchPaddingException - If the padding format is not supported
Return
The Cipher, initialized and ready to encrypt data with.
