Option "hash" renamed to "algorithm"

The option "hash" has been renamed to "algorithm" as this name represents the meaning better.

Hash algorithm name is mandatory

• "Hash type" has been renamed to "Hash algorithm".
• The hash algorithm must be specified. There is no longer a default algorithm. This has been changed so that the user is clear what hash algorithm he wants.

Allow hex characters as source

• Allow hex characters as source.
• Change options for encoding type to be more structured.

Print only the hash value in the chosen encoding

This releases simplifies the program quite a bit:

• It no longer prints the hash type, as it is specified on the command line.
• It only prints the hash value in one encoding. It is no longer possible to specify multiple encodings.

This simplifies the output. It is just one line with the hash in the chosen encoding. It is assumed that the caller knows which hash and which encoding were chosen.
