- 02
Optionally paste an expected checksum.
- 03
Calculate the digest and check the match result.
A few useful answers
Does a matching hash prove a file is safe?
It proves the bytes match that checksum. Trust still depends on where the expected checksum came from.
Which algorithm should I choose?
SHA-256 is a common choice for checksums. SHA-1 is provided for compatibility and should not be used for new security-sensitive designs.
