phpseclib / phpseclib
PHP Secure Communications Library - Pure-PHP implementations of RSA, AES, SSH2, SFTP, X.509 etc.
Maintainers
Requires
- php: >=5.6.1
- paragonie/constant_time_encoding: ^1|^2|^3
- paragonie/random_compat: ^1.4|^2.0|^9.99.99
Requires (Dev)
Suggests
- ext-dom: Install the DOM extension to load XML formatted public keys.
- ext-gmp: Install the GMP (GNU Multiple Precision) extension in order to speed up arbitrary precision integer arithmetic operations.
- ext-libsodium: SSH2/SFTP can make use of some algorithms provided by the libsodium-php extension.
- ext-mcrypt: Install the Mcrypt extension in order to speed up a few other cryptographic operations.
- ext-openssl: Install the OpenSSL extension in order to speed up a wide variety of cryptographic operations.
