SipHash for PHP
SipHash extension for PHP.
SipHash is a family of pseudorandom functions optimized for short inputs. Target applications include network traffic authentication and hash-table lookups protected against hash-flooding denial-of-service attacks. SipHash has well-defined security goals and competitive performance.
Usage:
sip_hash(key, message)
outputs siphash-2-4(key, message)
as a 8-byte string.
sip_hash32(key, message)
truncates the value and outputs a 32-bit integer.
The key
should be a 16 bytes string.
Installation
$ phpize
$ ./configure --enable-siphash
$ make install
And add extension=siphash.so
to your php.ini configuration file.
This PHP extension uses FloodyBerry's basic implementation
PHP 5.6+ and PHP 7.0+ are fully supported.
