Hash Bean

Properties Methods Events Configuration Settings Errors

The Hash component allows you to compute a hash using various algorithms.

Syntax

IPWorksEncrypt.Hash

Remarks

The Hash component allows you to compute a hash using various algorithms including SHA1, SHA224, SHA256, SHA384, SHA512, MD2, MD4, MD5, RIPEMD160, MD5SHA1, HMACMD5, HMACSHA1, HMACSHA224, HMACSHA256, HMACSHA384, HMACSHA512, etc.

To begin, first select the algorithm you wish to use when computing the hash. Common choices include MD5 and SHA1. For a full list of supported algorithms see the Algorithm property.

Next specify the data to hash. The component will determine the source of the input based on which properties are set.

The order in which the input properties are checked are as follows:

When a valid source is found the search stops.

Call the ComputeHash method to hash the data. The HashValue property will hold the computed hash. By default the hash value is hex encoded for ease of use, but you may disable this by setting EncodeHash to False.
