I'm collecting some info on the password hashing algorithms in use on various Unix systems. So far I have:
Does anyone have any more info? I'm particularly interested in what happened to $4$ and some info on which Microsoft hash is represented by $3$. And I would be interested to learn about any algorithms I missed.
Hi,
how can one find that which encryption algorithm the system is using for keeping the user password in the /etc/passwd or /etc/shadow file.
Is it
1: Hashing ( which considers only first 5 letters of password)
2: MD5 (Which allows arbitry length passwords)
Thanks,

Hello,
I'm having an issue with my password hashing. In /etc/shadow all the passwords hashes start with $1$. The security people want me to change it so the password hash starts with $5$ or $6$. So this is what I did to fix this.
I changed CRYPT_DEFAULT for 1 to 6
CRYPT_DEFAULT=6When I create a... (0 Replies)
So, I am writing a script that will read output from Bulk Extractor (which gathers data based on regular expressions). My script then reads the column that has the URL found, hashes it with MD5, then outputs the URL and hash to a file.
Where I am stuck on is that I want to read the bulk... (7 Replies)
Hi,
Our security audit person generated a report for Solaris-10 servers and mentioned this suggestion - "All passwords should be hashed using bcrypt. Solaris 10 supports this blowfish-based hash algorithm with the identifier 2a. To verify this, ensure the password hashes start with $2a$.... (2 Replies)

crypt_bsdmd5(5) Standards, Environments, and Macros crypt_bsdmd5(5)NAME
crypt_bsdmd5 - password hashing module using MD5 message hash algorithm
SYNOPSIS
/usr/lib/security/$ISA/crypt_bsdmd5.so
DESCRIPTION
The crypt_bsdmd5 module is a one-way password hashing module for use with crypt(3C) that uses the MD5 message hash algorithm. The algorithm
identifier for crypt.conf(4) and policy.conf(4) is 1. The output is compatible with md5crypt on BSD and Linux systems.
The maximum password length for crypt_bsdmd5 is 255 characters.
