Random Salt

Occasionally, I’m asked to provide a random list of characters that will be used as a salt for hashing a password or some data of some sort. The primary function of salts are to create a random one-way function typically used to fight against dictionary or rainbow table attacks. Here’s a neat command that you can generate from the Bash shell. It will generate a 32 random character string.

$ tr -c -d '0123456789abcdefghijklmnopqrstuvwxyz' </dev/urandom | dd bs=32 count=1 2>/dev/null;echo

$ tr -c -d '0123456789abcdefghijklmnopqrstuvwxyz' </dev/urandom | dd bs=32 count=1 2>/dev/null;echo

The result is: ynhgunq3ppnirhhp3vxpmvdw5b2uuc2f
