Raw RSA Key Handler| rsadp($c) X-Ref |
| RSADP See {@link http://tools.ietf.org/html/rfc3447#section-5.1.2 RFC3447#section-5.1.2}. param: \phpseclib3\Math\BigInteger $c return: bool|\phpseclib3\Math\BigInteger |
| rsasp1($m) X-Ref |
| RSASP1 See {@link http://tools.ietf.org/html/rfc3447#section-5.2.1 RFC3447#section-5.2.1}. param: \phpseclib3\Math\BigInteger $m return: bool|\phpseclib3\Math\BigInteger |
| exponentiate(BigInteger $x) X-Ref |
| Exponentiate param: \phpseclib3\Math\BigInteger $x return: \phpseclib3\Math\BigInteger |
| blind($x, $r, $i) X-Ref |
| Performs RSA Blinding Protects against timing attacks by employing RSA Blinding. Returns $x->modPow($this->exponents[$i], $this->primes[$i]) param: \phpseclib3\Math\BigInteger $x param: \phpseclib3\Math\BigInteger $r param: int $i return: \phpseclib3\Math\BigInteger |
| emsa_pss_encode($m, $emBits) X-Ref |
| EMSA-PSS-ENCODE See {@link http://tools.ietf.org/html/rfc3447#section-9.1.1 RFC3447#section-9.1.1}. param: string $m param: int $emBits return: string |
| rsassa_pss_sign($m) X-Ref |
| RSASSA-PSS-SIGN See {@link http://tools.ietf.org/html/rfc3447#section-8.1.1 RFC3447#section-8.1.1}. param: string $m return: bool|string |
| rsassa_pkcs1_v1_5_sign($m) X-Ref |
| RSASSA-PKCS1-V1_5-SIGN See {@link http://tools.ietf.org/html/rfc3447#section-8.2.1 RFC3447#section-8.2.1}. param: string $m return: bool|string |
| sign($message) X-Ref |
| Create a signature param: string $message return: string |
| rsaes_pkcs1_v1_5_decrypt($c) X-Ref |
| RSAES-PKCS1-V1_5-DECRYPT See {@link http://tools.ietf.org/html/rfc3447#section-7.2.2 RFC3447#section-7.2.2}. param: string $c return: bool|string |
| rsaes_oaep_decrypt($c) X-Ref |
| RSAES-OAEP-DECRYPT 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]. param: string $c return: bool|string |
| raw_encrypt($m) X-Ref |
| Raw Encryption / Decryption Doesn't use padding and is not recommended. param: string $m return: bool|string |
| decrypt($ciphertext) X-Ref |
| Decryption param: string $ciphertext return: bool|string |
| getPublicKey() X-Ref |
| Returns the public key return: mixed |
| toString($type, array $options = []) X-Ref |
| Returns the private key param: string $type param: array $options optional return: string |
