Function “calculateStrongChecksum”

function calculateStrongChecksum(path)

Calculates the "strong" checksum for a given file

This function calculates a SHA512-224 checksum of the file. This can be used to uniquely identify the file contents. For a faster check that usually yields a unique checksum, use calculateWeakChecksum first and only compute the strong checksum if the weak checksums are equal.

Parameters

Return Value

Returns the 224-bit checksum of the file encoded as a hex string.

Example

if (calculateStrongChecksum("image1.jpg") == calculateStrongChecksum("image2.jpg"))
	print("The two files are identical");
else
	print("The two files are not identical");
