getChecksumQuietly

public static String getChecksumQuietly(byte[] bytes,
                                        de.alpharogroup.crypto.algorithm.Algorithm algorithm)

Gets the checksum quietly from the given byte array with an instance of.

Parameters:

bytes - the byte array.

algorithm - the algorithm to get the checksum. This could be for instance "MD4", "MD5", "SHA-1", "SHA-256", "SHA-384" or "SHA-512".

Returns:

The checksum from the file as a String object.
