                                        InvalidAlgorithmParameterException

Decrypt a InputStream

Parameters:

inputStream - input stream

keyBase64 - keyBase64

ivBase64 - ivBase64

encMat - RemoteStoreFileEncryptionMaterial

Returns:

InputStream

Throws:

NoSuchPaddingException - when padding mechanism is not available for this environment

NoSuchAlgorithmException - when the requested algorithm is not available for this environment

InvalidKeyException - when there is an issue with the key value

BadPaddingException - when the data is not padded as expected

IllegalBlockSizeException - when the length of data is incorrect

InvalidAlgorithmParameterException - when the provided KeyStore has no trustAnchors
