Summary

Provides methods to sign and verify public key cryptography based digital signatures using any of the hashing algorithms as defined by HashAlgorithmName.

Methods

`NewKeyPair(keySize)`

Summary

Creates a new public/private key pair.

Returns

A new public/private key pair.

Parameters

Name	Type	Description
keySize	System.Int32	Size of the key.

`CreateSignature(data,privateKey,algorithm)`

Summary

Creates a signature for the given data using the specified private key and hash algorithm. Use one of the algorithms as defined by HashAlgorithmName.

Returns

The signature hash as base64 encoded string.

Parameters

Name	Type	Description
data	System.String	The data for which signature is to be computed.
privateKey	System.String	The private key.
algorithm	ASPSecurityKit.HashAlgorithmName	The algorithm.

Exceptions

Type	Description
System.ArgumentNullException	when data/privateKey is null or whitespace.

`VerifySignature(data,base64Signature,publicKey,algorithm)`

Summary

Verifies whether the given signature is valid for the given data using the specified public key and hash algorithm. You must specify the same algorithm used while computing the signature.

Returns

true if the signature is valid; otherwise, false.

Parameters

Name	Type	Description
data	System.String	The data for which signature is to be verified.
base64Signature	System.String	The base64 signature.
publicKey	System.String	The public key.
algorithm	ASPSecurityKit.HashAlgorithmName	The algorithm.

Exceptions

Type	Description
System.ArgumentNullException	when data, base64Signature or publicKey is null or whitespace.
