Checksum

Do you need to confirm the file you are sharing with another is the same file you sent to them. Use a hash.

The Checksum Third Party Application allows you to generate a hash of the file. There are multiple hashes available including: MD5, SHA1, SHA256, SHA384, SHA512, CRC32, and CRC32b.

Note this hash can only be performed on individual files, and not on shared folders.
