DecryptUpdate Method

Decrypts the next block of encrypted data.

Syntax

public func decryptUpdate(buffer: Data) throws -> Data

Remarks

When using block-by-block decryption, pass every subsequent block of the encryptedmessage to this method until the entire message is processed. For each encryptedblock the method returns a piece of decrypted data.

Please note that in general case there is no direct correspondence between the data actuallycontained in the encrypted block with the output of this method. The component maychoose to cache a piece of the provided buffer internally if it doesn't constitutea full block of encrypted data.

Remember to call DecryptInit before calling this method to prepare the controlfor the decryption process.
