If you want to convert a passphrase to a key, use a suitable (Obviously don't use this example key for anything Load your secret key from a safe place and reuse it across multiple For a description of the methodology, see Open(dst, nonce, ciphertext, additionalData byte) ( byte, error)ĪEAD is a cipher mode providing authenticated encryption with associatedĭata. // Even if the function fails, the contents of dst, up to its capacity, // may be overwritten. Otherwise, the remaining capacity of dst must not overlap plaintext. // To reuse ciphertext's storage for the decrypted output, use ciphertext // as dst. The nonce must be NonceSize() // bytes long and both it and the additional data must match the // value passed to Seal. Seal(dst, nonce, plaintext, additionalData byte) byte // Open decrypts and authenticates ciphertext, authenticates the // additional data and, if successful, appends the resulting plaintext // to dst, returning the updated slice. // To reuse plaintext's storage for the encrypted output, use plaintext // as dst. The nonce must be NonceSize() bytes long and unique for all // time, for a given key. Overhead() int // Seal encrypts and authenticates plaintext, authenticates the // additional data and appends the result to dst, returning the updated // slice. NonceSize() int // Overhead returns the maximum difference between the lengths of a // plaintext and its ciphertext.
