| rsavp1($s) X-Ref |
| RSAVP1 See {@link http://tools.ietf.org/html/rfc3447#section-5.2.2 RFC3447#section-5.2.2}. return: bool|\phpseclib3\Math\BigInteger param: \phpseclib3\Math\BigInteger $s |

| RSASSA-PKCS1-V1_5-VERIFY See {@link http://tools.ietf.org/html/rfc3447#section-8.2.2 RFC3447#section-8.2.2}. return: bool param: string $m param: string $s |
| rsassa_pkcs1_v1_5_relaxed_verify($m, $s) X-Ref |
| RSASSA-PKCS1-V1_5-VERIFY (relaxed matching) Per {@link http://tools.ietf.org/html/rfc3447#page-43 RFC3447#page-43} PKCS1 v1.5 specified the use BER encoding rather than DER encoding that PKCS1 v2.0 specified. This means that under rare conditions you can have a perfectly valid v1.5 signature that fails to validate with _rsassa_pkcs1_v1_5_verify(). PKCS1 v2.1 also recommends that if you're going to validate these types of signatures you "should indicate whether the underlying BER encoding is a DER encoding and hence whether the signature is valid with respect to the specification given in [PKCS1 v2.0+]". so if you do $rsa->getLastPadding() and get RSA::PADDING_RELAXED_PKCS1 back instead of RSA::PADDING_PKCS1... that means BER encoding was used. return: bool param: string $m param: string $s |

| EMSA-PSS-VERIFY See {@link http://tools.ietf.org/html/rfc3447#section-9.1.2 RFC3447#section-9.1.2}. return: string param: string $m param: string $em param: int $emBits |

| Verifies a signature return: bool see: self::sign() param: string $message param: string $signature |
| rsaes_pkcs1_v1_5_encrypt($m, $pkcs15_compat = false) X-Ref |
| RSAES-PKCS1-V1_5-ENCRYPT See {@link http://tools.ietf.org/html/rfc3447#section-7.2.1 RFC3447#section-7.2.1}. return: bool|string param: string $m param: bool $pkcs15_compat optional |

| rsaep($m) X-Ref |
| RSAEP See {@link http://tools.ietf.org/html/rfc3447#section-5.1.1 RFC3447#section-5.1.1}. return: bool|\phpseclib3\Math\BigInteger param: \phpseclib3\Math\BigInteger $m |
| raw_encrypt($m) X-Ref |
| Raw Encryption / Decryption Doesn't use padding and is not recommended. return: bool|string param: string $m |
| encrypt($plaintext) X-Ref |
| Encryption Both self::PADDING_OAEP and self::PADDING_PKCS1 both place limits on how long $plaintext can be. If $plaintext exceeds those limits it will be broken up so that it does and the resultant ciphertext's will be concatenated together. return: bool|string see: self::decrypt() param: string $plaintext |
| toString($type, array $options = []) X-Ref |
| Returns the public key The public key is only returned under two circumstances - if the private key had the public key embedded within it or if the public key was set via setPublicKey(). If the currently loaded key is supposed to be the public key this function won't return it since this library, for the most part, doesn't distinguish between public and private keys. return: mixed param: string $type param: array $options optional |
| asPrivateKey() X-Ref |
| Converts a public key to a private key return: RSA |
