setExponent($val) X-Ref |
Sets the public exponent for key generation This will be 65537 unless changed. param: int $val |
setSmallestPrime($val) X-Ref |
Sets the smallest prime number in bits. Used for key generation This will be 4096 unless changed. param: int $val |
setOpenSSLConfigPath($val) X-Ref |
Sets the OpenSSL config file path Set to the empty string to use the default config file param: string $val |
createKey($bits = 2048) X-Ref |
Create a private key The public key can be extracted from the private key param: int $bits return: RSA |
onLoad($components) X-Ref |
OnLoad Handler param: array $components return: bool |
initialize_static_variables() X-Ref |
Initialize static variables |
__construct() X-Ref |
Constructor PublicKey and PrivateKey objects can only be created from abstract RSA class |
i2osp($x, $xLen) X-Ref |
Integer-to-Octet-String primitive See {@link http://tools.ietf.org/html/rfc3447#section-4.1 RFC3447#section-4.1}. param: bool|\phpseclib3\Math\BigInteger $x param: int $xLen return: bool|string |
os2ip($x) X-Ref |
Octet-String-to-Integer primitive See {@link http://tools.ietf.org/html/rfc3447#section-4.2 RFC3447#section-4.2}. param: string $x return: \phpseclib3\Math\BigInteger |
emsa_pkcs1_v1_5_encode($m, $emLen) X-Ref |
EMSA-PKCS1-V1_5-ENCODE See {@link http://tools.ietf.org/html/rfc3447#section-9.2 RFC3447#section-9.2}. param: string $m param: int $emLen return: string |
emsa_pkcs1_v1_5_encode_without_null($m, $emLen) X-Ref |
EMSA-PKCS1-V1_5-ENCODE (without NULL) Quoting https://tools.ietf.org/html/rfc8017#page-65, "The parameters field associated with id-sha1, id-sha224, id-sha256, id-sha384, id-sha512, id-sha512/224, and id-sha512/256 should generally be omitted, but if present, it shall have a value of type NULL" param: string $m param: int $emLen return: string |
mgf1($mgfSeed, $maskLen) X-Ref |
MGF1 See {@link http://tools.ietf.org/html/rfc3447#appendix-B.2.1 RFC3447#appendix-B.2.1}. param: string $mgfSeed param: int $maskLen return: string |
getLength() X-Ref |
Returns the key size More specifically, this returns the size of the modulo in bits. return: int |
withHash($hash) X-Ref |
Determines which hashing function should be used Used with signature production / verification and (if the encryption mode is self::PADDING_OAEP) encryption and decryption. param: string $hash |
withMGFHash($hash) X-Ref |
Determines which hashing function should be used for the mask generation function The mask generation function is used by self::PADDING_OAEP and self::PADDING_PSS and although it's best if Hash and MGFHash are set to the same thing this is not a requirement. param: string $hash |
getMGFHash() X-Ref |
Returns the MGF hash algorithm currently being used |
withSaltLength($sLen) X-Ref |
Determines the salt length Used by RSA::PADDING_PSS To quote from {@link http://tools.ietf.org/html/rfc3447#page-38 RFC3447#page-38}: Typical salt lengths in octets are hLen (the length of the output of the hash function Hash) and 0. param: int $sLen |
getSaltLength() X-Ref |
Returns the salt length currently being used |
withLabel($label) X-Ref |
Determines the label Used by RSA::PADDING_OAEP To quote from {@link http://tools.ietf.org/html/rfc3447#page-17 RFC3447#page-17}: Both the encryption and the decryption operations of RSAES-OAEP take the value of a label L as input. In this version of PKCS #1, L is the empty string; other uses of the label are outside the scope of this document. param: string $label |
getLabel() X-Ref |
Returns the label currently being used |
withPadding($padding) X-Ref |
Determines the padding modes Example: $key->withPadding(RSA::ENCRYPTION_PKCS1 | RSA::SIGNATURE_PKCS1); param: int $padding |
getPadding() X-Ref |
Returns the padding currently being used |
getEngine() X-Ref |
Returns the current engine being used OpenSSL is only used in this class (and it's subclasses) for key generation Even then it depends on the parameters you're using. It's not used for multi-prime RSA nor is it used if the key length is outside of the range supported by OpenSSL return: string |
enableBlinding() X-Ref |
Enable RSA Blinding |
disableBlinding() X-Ref |
Disable RSA Blinding |
