Instance Methodswift-crypto 3.8.0Crypto
open(_:)
Decrypts a message, if the ciphertext is valid.
HPKE.swift:314mutating func open<C>(_ ciphertext: C) throws -> Data where C : DataProtocol Parameters
- ciphertext
The ciphertext message to decrypt.
Returns
The resulting cleartext message if the message is authentic.
You can call this method multiple times to decrypt a series of messages. When using this method, the recipient of the ciphertext messages needs to decrypt them in the same order that the sender encrypts them.
