PBKDF2 hashing for Bash
|
|
|
|
## USAGE
|
|
|
|
```
|
|
$ bash pbkdf2.sh *hashtype* *salt* *password* *iterations* *{raw/full/rawfull}*
|
|
```
|
|
|
|
or
|
|
|
|
```
|
|
$ ./pbkdf2.sh *hashtype* *salt* *password* *iterations* *{raw/full/rawfull}*
|
|
```
|
|
|
|
### hashtype *string*
|
|
|
|
Options: md5, sha1, sha224, sha256, sha384, sha512, blake2b, blake2s, sha3_224, sha3_256, sha3_384, sha3_512, shake_128, shake_256
|
|
|
|
### salt *string*
|
|
|
|
This must be a predefind string of A-Z, a-z and 0-9.
|
|
|
|
### password *string*
|
|
|
|
This must be a predefind string of A-Z, a-z and 0-9.
|
|
|
|
### iterations *integer*
|
|
|
|
Range 1 to 2147483647. The higher the integer the more secure but at the cost of time.
|
|
|
|
### {raw/full/rawfull} *optional*
|
|
|
|
This is optional. By default you will get a hash string followed by a new line. If you do not want the new line, say to use in a variable, then use 'raw' to get just the hash in hex. However if you use 'full', you will get a string that can be used to input into a database with a new line at the end. Use 'rawfull' to return the string without the new line.

# What is PBKDF2?
|
|
|
|
> PBKDF2 applies a pseudorandom function, such as hash-based message authentication code (HMAC), to the input password or passphrase along with a salt value and repeats the process many times to produce a derived key, which can then be used as a cryptographic key in subsequent operations. The added computational work makes password cracking much more difficult, and is known as key stretching.
|
|
*[Source: Wikipedia](https://en.wikipedia.org/wiki/PBKDF2)*
|
|
|
|
PBKDF2 is used in many applications where a password needs to be stored for future verification. Unlike just using a straight Hashing Algorithm, PBKDF2 uses a "salt" along side the password, and rehashes repeatedly according to the number of "iterations".
