sodium_crypto_box_open
Authenticated public-key decryption
Description
stringfalse sodium_crypto_box_open(string $ciphertext, string $nonce, #[\SensitiveParameter]string $key_pair)
Decrypt a message using asymmetric (public key) cryptography.
Parameters
-
ciphertext
-
The encrypted message to attempt to decrypt.
-
nonce
-
A number that must be only used once, per message. 24 bytes long.
This is a large enough bound to generate randomly (i.e. random_bytes).
-
key_pair
-
See sodium_crypto_box_keypair_from_secretkey_and_publickey.
This should include the sender's public key and the recipient's secret key.
Return Values
Returns the plaintext message on success, or false on failure.
