The “Hash Calculator” node allows to calculate hash values aka. “digests” for given string or binary cells using various hash functions. Hash functions have a broad usage in information-security, e.g. for digital signatures, message authentication codes (MACs), and general authentication. Also they can be used to index data, create fingerprints, detect duplicates and uniquely identify files.
The following algorithms are currently supported out of the box (Provider “SUN”):
Additionally, the following hashing algorithms are provided via an extension point:

The result is given in
hexadecimal
form. For example, the string “Lorem ipsum dolor sit amet” is
transformed to an SHA hash
38f00f8738e241daea6f37f6f55ae8414d7b0219.
Input cannot only be provided as string data, but also as binary cell. In this case, the hashes are calculated in a streaming manner, which means, that hashes can also be calculated for binary data which exceed the amount of available memory.
