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-openssl: Install the OpenSSL extension in order to speed up a wide variety of cryptographic operations.
  • react/async: Use SSH2 async I/O mode (constructor flag) with React\EventLoop; same integration style as non-blocking stream + await().
