open fun createDecryptCipher(iv: ByteArray): Cipher (source)
Create a cipher initialized for decrypting 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 stored ciphertext or decryption will fail.
iv - The initialization vector/nonce to decrypt with
GeneralSecurityException - If the cipher could not be created and initialized
Return
The Cipher, initialized and ready to decrypt data with.
