PHP Class ParagonIE\Halite\File

Cryptography operations for the filesystem. This library makes heavy use of return-type declarations, which are a PHP 7 only feature. Read more about them here: Afficher le fichier Open project: paragonie/halite Class Usage Examples

Méthodes publiques

Méthode	Description
checksum ( string | resource $filePath, Key $key = null, boolean $raw = false ) : string	Calculate the BLAKE2b-512 checksum of a file. This method doesn't load the entire file into memory. You may optionally supply a key to use in the BLAKE2b hash.
checksum ( string | resource $filePath, Key $key = null, mixed $encoding = Halite::ENCODE_BASE64URLSAFE ) : string	Calculate the BLAKE2b-512 checksum of a file. This method doesn't load the entire file into memory. You may optionally supply a key to use in the BLAKE2b hash.
decrypt ( string | resource $input, string | resource $output, EncryptionKey $key ) : boolean	Decrypt a file using symmetric-key authenticated encryption.
encrypt ( string | resource $input, string | resource $output, EncryptionKey $key ) : integer	Encrypt a file using symmetric authenticated encryption.
seal ( string | resource $input, string | resource $output, EncryptionPublicKey $publicKey ) : integer	Encrypt a file using anonymous public-key encryption (with ciphertext authentication).
sign ( string | resource $filename, SignatureSecretKey $secretKey, boolean $raw_binary = false ) : string	Calculate a digital signature (Ed25519) of a file
sign ( string | resource $filename, SignatureSecretKey $secretKey, mixed $encoding = Halite::ENCODE_BASE64URLSAFE ) : string	Calculate a digital signature (Ed25519) of a file
unseal ( string | resource $input, string | resource $output, EncryptionSecretKey $secretKey ) : boolean	Decrypt a file using anonymous public-key encryption. Ciphertext integrity is still assured thanks to the Encrypt-then-MAC construction.
verify ( string | resource $filename, SignaturePublicKey $publicKey, string $signature, boolean $raw_binary = false ) : boolean	Verify a digital signature for a file.
verify ( string | resource $filename, SignaturePublicKey $publicKey, string $signature, mixed $encoding = Halite::ENCODE_BASE64URLSAFE ) : boolean	Verify a digital signature for a file.
