Manual
sodium_crypto_box_open(
string$ciphertext,
string$nonce,
string$key_pair ): string|false
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.
