What would you like to do?
pyhash -- quickly hash some text with md5, sha1, or sha256. Works with piping input.
#!/usr/bin/env python2.7
#
# Install this in your PATH as `pyhash`.
#
# curl https://gist.github.com/jbenet/6502583/raw/pyhash.py -o pyhash
# mv pyhash /usr/bin/local/pyhash
# chmod +x /usr/bin/local/pyhash
#
# If you want more cryptographic hashing functions, try the PassLib module.
#
# Don't use this script for anything security related!
import hashlib
algorithms = dict(
md5 = lambda s: hashlib.md5(s).hexdigest(),
sha1 = lambda s: hashlib.sha1(s).hexdigest(),
sha256 = lambda s: hashlib.sha256(s).hexdigest(),
)
def usage():
print 'Usage:', sys.argv[0], '<algorithm> [text to hash]'
print 'Available algorithms:'
for algo in algorithms:
print '\t', algo
if __name__ == '__main__':
import sys
try:
algo = algorithms[sys.argv[1]]
except (KeyError, IndexError):
usage()
sys.exit(1)
if len(sys.argv) > 2:
text = sys.argv[2]
else:
text = sys.stdin.read()
print algo(text)

The md5 lambda function (L10) uses the wrong argument. I made some other minor changes in my fork, if you're interested.

I wrote something similar a while ago, but with the option of adding salts when hashing text. It's here if you want to check it out.
