Class for decoding DSA key pairs from ASN.1 DER encoding.
| IMPORT_C void | DecodeDERL | ( | const TDesC8 & | aDER, |
| TInt & | aPos, | |||
| CDSAPublicKey *& | aPublicKey, | |||

| ) | ||||
Decodes a DSA key pair from a buffer containing an ASN.1 DER-encoded private key.
The encoding of the private key contains public key components as well.
* SEQUENCE-OF
* INTEGER version (==0, ignored)
* INTEGER p (public prime)
* INTEGER q (160-bit public subprime, q | p-1)
* INTEGER g (public generator of subgroup)
* INTEGER x (private key)
* INTEGER y (public key y=g^x)

| Parameter | Description |
|---|---|
| aDER | DER-encoded private key. |
| aPos | Position in the buffer to start decoding (updated on exit). |
| aPublicKey | On return, the DSA public key object |
| aPrivateKey | On return, the DSA private key object |
