Functions that are not part of a class:

rsadp(BigInteger $c)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-5.1.2 RFC3447#section-5.1.2}.

return: bool|\phpseclib3\Math\BigInteger

rsasp1(BigInteger $m)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-5.2.1 RFC3447#section-5.2.1}.

return: bool|\phpseclib3\Math\BigInteger

exponentiate(BigInteger $x)   X-Ref

return: \phpseclib3\Math\BigInteger
param: \phpseclib3\Math\BigInteger $x

blind(BigInteger $x, BigInteger $r, $i)   X-Ref
Performs RSA Blinding

Protects against timing attacks by employing RSA Blinding.
Returns $x->modPow($this->exponents[$i], $this->primes[$i])

return: \phpseclib3\Math\BigInteger
param: \phpseclib3\Math\BigInteger $x
param: \phpseclib3\Math\BigInteger $r
param: int $i

emsa_pss_encode($m, $emBits)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-9.1.1 RFC3447#section-9.1.1}.

return: string
param: string $m
param: int $emBits

rsassa_pss_sign($m)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-8.1.1 RFC3447#section-8.1.1}.

return: bool|string
param: string $m

rsassa_pkcs1_v1_5_sign($m)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-8.2.1 RFC3447#section-8.2.1}.

return: bool|string
param: string $m

sign($message)   X-Ref
Create a signature

return: string
param: string $message
see: self::verify()

rsaes_pkcs1_v1_5_decrypt($c)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-7.2.2 RFC3447#section-7.2.2}.

return: bool|string
param: string $c

rsaes_oaep_decrypt($c)   X-Ref

See {@link http://tools.ietf.org/html/rfc3447#section-7.1.2 RFC3447#section-7.1.2}.  The fact that the error
messages aren't distinguishable from one another hinders debugging, but, to quote from RFC3447#section-7.1.2:

Note.  Care must be taken to ensure that an opponent cannot
distinguish the different error conditions in Step 3.g, whether by
error message or timing, or, more generally, learn partial
information about the encoded message EM.  Otherwise an opponent may
be able to obtain useful information about the decryption of the
ciphertext C, leading to a chosen-ciphertext attack such as the one
observed by Manger [36].

return: bool|string
param: string $c

raw_encrypt($m)   X-Ref
Raw Encryption / Decryption

Doesn't use padding and is not recommended.

return: bool|string
param: string $m

decrypt($ciphertext)   X-Ref

return: bool|string
param: string $ciphertext
see: self::encrypt()

getPublicKey()   X-Ref
Returns the public key

return: mixed

toString($type, array $options = [])   X-Ref
Returns the private key

return: string
param: string $type
param: array $options optional
