Méthodes publiques

Méthode Description
decryptFile ( string $inputFilename, string $outputFilename, Defuse\Crypto\Key $key ) Decrypts the input file, saving the plaintext to the output file.
decryptFileWithPassword ( string $inputFilename, string $outputFilename, string $password ) Decrypts a file with a password, using a slow key derivation function to make password cracking more expensive.
decryptResource ( resource $inputHandle, resource $outputHandle, Defuse\Crypto\Key $key ) Takes two resource handles and decrypts the contents of the first, writing the plaintext into the second.
decryptResourceInternal ( resource $inputHandle, resource $outputHandle, KeyOrPassword $secret ) Decrypts a file-backed resource with either a key or a password.
decryptResourceWithPassword ( resource $inputHandle, resource $outputHandle, string $password ) Decrypts the contents of one resource into another with a password, using a slow key derivation function to make password cracking more expensive.
encryptFile ( string $inputFilename, string $outputFilename, Defuse\Crypto\Key $key ) Encrypts the input file, saving the ciphertext to the output file.
encryptFileWithPassword ( string $inputFilename, string $outputFilename, string $password ) Encrypts a file with a password, using a slow key derivation function to make password cracking more expensive.
encryptResource ( resource $inputHandle, resource $outputHandle, Defuse\Crypto\Key $key ) Takes two resource handles and encrypts the contents of the first, writing the ciphertext into the second.
encryptResourceWithPassword ( resource $inputHandle, resource $outputHandle, string $password ) Encrypts the contents of one resource handle into another with a password, using a slow key derivation function to make password cracking more expensive.
readBytes ( resource $stream, integer $num_bytes ) : string Read from a stream; prevent partial reads.
writeBytes ( resource $stream, string $buf, integer $num_bytes = null ) : string Write to a stream; prevents partial writes.
