Use a java routine to calculate MD5 hash of a file
Updated 12 Jul 2017

View License

This function attempts to calculate a MD5 checksum of a file. It is returned as a 32 character string - lower case hexadecimal.
This file is a one-file implementation. The code is concise and can also be included in your own functions. The purpose of this is to avoid having to compile c-code into mex files for simple implementations.
MD5 checksums should be used only to check for the file integrity. They are cryptographically broken, and unsuitable for security purposes.
