fileToCalculate - File to calculate

algorithms - Algorithms to use for calculation

Returns:

Map with algorithm keys and checksum values

Throws:

java.security.NoSuchAlgorithmException - Thrown if any of the given algorithms aren't supported

java.io.IOException - Thrown if any error occurs while reading the file or calculating the checksums

java.lang.IllegalArgumentException - TThrown if the given file to calc is null or non-existing or the algorithms var args is null
