getChecksum

public String getChecksum(String fileName,
                          String algorithm)

Get the digest of a closed file

Parameters:

fileName - the file name to get the digest for

algorithm - the digest algorithm

Returns:

the digest or null if the digest was not requested. The digest will be lower case hex encoded.

Throws:
