getPublicKey()
sign()
toString()
Class: PrivateKey - X-Ref
DSA Private Key| getPublicKey() X-Ref |
| Returns the public key If you do "openssl rsa -in private.rsa -pubout -outform PEM" you get a PKCS8 formatted key that contains a publicKeyAlgorithm AlgorithmIdentifier and a publicKey BIT STRING. An AlgorithmIdentifier contains an OID and a parameters field. With RSA public keys this parameters field is NULL. With DSA PKCS8 public keys it is not - it contains the p, q and g variables. The publicKey BIT STRING contains, simply, the y variable. This can be verified by getting a DSA PKCS8 public key: "openssl dsa -in private.dsa -pubout -outform PEM" ie. just swap out rsa with dsa in the rsa command above. A PKCS1 public key corresponds to the publicKey portion of the PKCS8 key. In the case of RSA the publicKey portion /is/ the key. In the case of DSA it is not. You cannot verify a signature without the parameters and the PKCS1 DSA public key format does not include the parameters. return: mixed |
