Detailed Description

The actions creates a hash values of datasets, the first argument is the name of the hasing algorithm (Adler-32, CRC-32, CRC-32C, Murmur3-32, Murmur3-128, Siphash-2-4, MD2, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512), for all other unflatten arguments a hash value is calculated and the action returns the hash values back and never fails

[Hash1 | Hash2 | Hash3] = crypto/hash( "Adler-32 | CRC-32 | CRC-32C | ...", Dataset1, Dataset2, Dataset3 );
