Sets a number of bytes to be generated by the openssl pseudo random generator

public getRandomBytes ()

Returns a number of bytes to be generated by the openssl pseudo random generator

public getRandom ()

Returns a secure random number generator instance

public getSaltBytes ([mixed $numberBytes])

Generate a >22-length pseudo random string to be used as salt for passwords

public hash (mixed $password, [mixed $workFactor])

Creates a password hash using bcrypt with a pseudo random salt

public checkHash (mixed $password, mixed $passwordHash, [mixed $maxPassLength])

Checks a plain text password and its hash version to check if the password matches

public isLegacyHash (mixed $passwordHash)

Checks if a password hash is a valid bcrypt’s hash

public getTokenKey ()

Generates a pseudo random token key to be used as input’s name in a CSRF check

public getToken ()

Generates a pseudo random token value to be used as input’s value in a CSRF check

Sets the default hash

public getDefaultHash ()

Returns the default hash

public hasLibreSsl ()

Testing for LibreSSL

public getSslVersionNumber ()

Getting OpenSSL or LibreSSL version Parse OPENSSL_VERSION_TEXT because OPENSSL_VERSION_NUMBER is no use for LibreSSL.
