PHP Class Defuse\Crypto\Crypto

Public Methods

Method	Description
decrypt ( string $ciphertext, Defuse\Crypto\Key $key, boolean $raw_binary = false ) : string	Decrypts a ciphertext to a string with a Key.
decryptWithPassword ( string $ciphertext, string $password, boolean $raw_binary = false ) : string	Decrypts a ciphertext to a string with a password, using a slow key derivation function to make password cracking more expensive.
encrypt ( string $plaintext, Defuse\Crypto\Key $key, boolean $raw_binary = false ) : string	Encrypts a string with a Key.
encryptWithPassword ( string $plaintext, string $password, boolean $raw_binary = false ) : string	Encrypts a string with a password, using a slow key derivation function to make password cracking more expensive.
legacyDecrypt ( string $ciphertext, string $key ) : string	Decrypts a legacy ciphertext produced by version 1 of this library.

Method	Description
plainDecrypt ( string $ciphertext, string $key, string $iv, string $cipherMethod ) : string	Raw unauthenticated decryption (insecure on its own).
plainEncrypt ( string $plaintext, string $key, string $iv ) : string	Raw unauthenticated encryption (insecure on its own).
verifyHMAC ( string $correct_hmac, string $message, string $key ) : boolean	Verifies an HMAC without leaking information through side-channels.

Method	Description
decryptInternal ( string $ciphertext, KeyOrPassword $secret, boolean $raw_binary ) : string	Decrypts a ciphertext to a string with either a key or a password.
encryptInternal ( string $plaintext, KeyOrPassword $secret, boolean $raw_binary ) : string	Encrypts a string with either a key or a password.
