Member Attribute Documentation

iPrivateKey

const CDSAPrivateKey &iPrivateKey[protected]

The DSA private key to be used for signing

Constructor & Destructor Documentation

CDSASigner ( const CDSAPrivateKey & )

CDSASigner(const CDSAPrivateKey &aKey)[protected]

Member Function Documentation

MaxInputLength ( void )

TInt MaxInputLength(void)const [virtual]

NewL ( const CDSAPrivateKey & )

IMPORT_C CDSASigner *NewL(const CDSAPrivateKey &aKey)[static]

Creates a new CDSASigner object from a specified DSA private key.

ParameterDescription
aKeyThe DSA private key to be used for signing

Returns: A pointer to the new CDSASigner object

NewLC ( const CDSAPrivateKey & )

IMPORT_C CDSASigner *NewLC(const CDSAPrivateKey &aKey)[static]

Creates a new CDSASigner object from a specified DSA private key.

The returned pointer is put onto the cleanup stack.

ParameterDescription
aKeyThe DSA private key to be used for signing

Returns: A pointer to the new CDSASigner object

SignL ( const TDesC8 & )

CDSASignature *SignL(const TDesC8 &aInput)const [virtual]

Digitally signs the specified input message

Note that in order to be interoperable and compliant with the DSS, aInput must be the result of a SHA-1 hash.

panic
ECryptoPanicInputTooLarge If aInput is larger than MaxInputLength(), which is likely to happen if the caller has passed in something that has not been hashed.
ParameterDescription
aInputA SHA-1 hash of the message to sign

Returns: A pointer to a new CSignature object
