A Python MD5 hash is different than the one created by the md5sum command on the shell. Why?
>>> import hashlib >>> h = hashlib.md5() >>> h.update("mystringforhash") >>> print h.hexdigest() 86b6423cb6d211734fc7d81bbc5e11d3 # Result from Python $ echo mystringforhash | md5sum 686687dd68c5de717b34569dbfb8d3c3 - # Result on the shell

The md5sum command is based on the MD5 algorithm and generates 128-bit message digests. The md5sum command enables you to verify the integrity of files downloaded over a network connection. You can also use the md5sum command to compare files and verify the integrity of files.
md5sum is a computer program that calculates and verifies 128-bit MD5 hashes, as described in RFC 1321. The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash.
echo appends a \n since you usually do not want lines not ending with a linebreak in your shell (it looks really ugly if the prompt does not start at the very left).
Use the -n argument to omit the trailing linebreak and it will print the same checksum as your python script:
> echo -n mystringforhash | md5sum 86b6423cb6d211734fc7d81bbc5e11d3 - If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
