HashValue Property

The hash value of the data.

Syntax

property HashValue: String read get_HashValue write set_HashValue;
property HashValueB: TBytes read get_HashValueB write set_HashValueB;

Default Value

''

Remarks

This property holds the computed hash value for the specified data. This is populated when calling Sign or VerifySignature when an input file is specified by setting InputFile or InputMessage.

If you know the hash value prior to using the component you may specify the pre-computed hash value here.

Hash Notes

The component will determine whether or not to recompute the hash based on the properties that are set. If a file is specified by InputFile or InputMessage the hash will be recomputed when calling Sign or VerifySignature. If the HashValue property is set the component will only sign the hash or verify the hash signature. Setting InputFile or InputMessage clears the HashValue property. Setting the HashValue property clears the input file selection.
