| RSAES-PKCS1-V1_5-DECRYPT 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 |
| 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]. return: bool|string param: string $c |

| getPublicKey() X-Ref |
