Implementation of DSA signature verification as specified in FIPS 186-2 change request 1.
| const CDSAPublicKey & | iPublicKey | [protected] |
The DSA public key to be used for verification
| IMPORT_C CDSAVerifier * | NewL | ( | const CDSAPublicKey & | aKey | ) | [static] |
Creates a new CDSAVerifier object from a specified DSA public key.
| Parameter | Description |
|---|---|
| aKey | The DSA public key to be used for verifying |
Returns: A pointer to the new CDSAVerifier object
| IMPORT_C CDSAVerifier * | NewLC | ( | const CDSAPublicKey & | aKey | ) | [static] |
Creates a new CDSAVerifier object from a specified DSA public key.
The returned pointer is put onto the cleanup stack.
| Parameter | Description |
|---|---|
| aKey | The DSA public key to be used for verifying |
Returns: A pointer to the new CDSAVerifier object
| TBool | VerifyL | ( | const TDesC8 & | aInput, |
| const CDSASignature & | aSignature | |||
| ) | const [virtual] | |||
Verifies the specified digital signature
Note that in order to be interoperable and compliant with the DSS, aInput must be the result of a SHA-1 hash.
| Parameter | Description |
|---|---|
| aInput | A SHA-1 hash of the received message |
| aSignature | The signature to be verified |
Returns: Whether the signature is the result of signing aInput with the supplied key
