Blowfish hashed passwords

The implementation looks like a single function to generate the hash. I?m not much of a programmer, but it would seem to me that these .c/.h files

Blowfish hashed passwords
> I would love to know why your ubuntu 14.04 system doesn't support sha512-crypt. I just tried SHA512-CRYPT and it is supported on Ubuntu 14.04. I think I was thinking about DBMail instead of Dovecot. I could really use support for BLF-CRYPT since my current password hashes generated by PHP are using Blowfish encryption. Maybe, Dovecot could just add support for BLF-CRYPT by using the

Fatal: Unknown scheme: SHA512-CRYPT. On a Mac-mini
Running postfix+dovecot+mysql on a mac-mini, and trying to solve this puzzle. Is this a Mac issue?, a MySQL issue? or something I haven't configured in? You can see from the output of the samples shows in the first case, that SHA512-CRYPT seems to be Unknown. The code I used is from a Linux based tutorial on setting up Postfix+Dovecot+MySQL on a site. Everything is generally going ok, apart

Changing Password Schemes
That's not SHA512-CRYPT. That's just a simple sha512 of the password, without salt. A SHA512-CRYPT password will be generated with: printf "1234\n1234" | doveadm pw -s SHA512-CRYPT or: doveadm pw -s SHA512-CRYPT -p 1234 or: mkpasswd -m sha-512 1234 (without the "{SHA512-CRYPT}" prefix) What exactly is the difficulty you are having with converting the passwords?

Need help with Decryption using blowfish CBC
Hello all, Hoping someone can help me out here. I''ve burned almost a week trying to figure out how to decrypt an image file that has been encrypted using Blowfish CBC. I found some code on the net and have modified as follows: require ''openssl'' require ''digest/sha1'' ivArr = [0x0D, 0x0E, 0x0A, 0x0D, 0x0F, 0x0A, 0x0C, 0x0E ]

Strange behaviour with BLF-CRYPT and SHA*-CRYPT pasword schemas

most secure password scheme
Hello, I have a few questions on password schemes. Is SHA512 the most secure? Is there a difference between SHA512 and SHA512-CRYPT? What about SSHA512 and SSH512-CRYPT? Is there a problem with this sql statement: UPDATE virtual_users SET password=CONCAT(?{SHA256-CRYPT}?, ENCRYPT (?Password Goes Here?, CONCAT(?$5$?, SUBSTRING(SHA(RAND()), -16)))) WHERE user=?user at example.com?; I'm

Is there any explanation for this behaviour though? Why are BCRYPT hashes accepted when default_pass_scheme is set to SHA512-CRYPT and not vice versa? Is this

Bug in Dovecot 1.0.5 - CRYPT-MD5 not working
Problem: Using MySQL storage for the user and password db with MD5-CRYPT hashes, Dovecot fails to successfully authenticate when the MD5-CRYPT or MD5 settings are specified as default_pass_scheme in dovecot-mysql.conf. Dovecot /does/ successfully authenticate against MD5-CRYPT hashes when default_pass_scheme is set to CRYPT, which according to the docs should be DES encryption. (I do not

CRYPT scheme and 8 character limit
I've decided that having users supply cleartext passwords for me to encrypt and encode is a bad idea, anyway. So maybe I won't need dovecotpw. The idea is that users supply an already-encrypted password. Most of the users can fetch their login password from /etc/shadow on their own computer. Wiki page http://wiki.dovecot.org/Authentication/PasswordSchemes indicates that scheme name

most secure password scheme
Hello, Thanks for the explanation. So should I go with SSHA512 or SHA512-CRYPT? From your explanation i'm interpreting to mean that SHA512-CRYPT also salts. This is for storing in a mysql database. Also, what should the password field length and type be set for? Currently it's varchar(128) Thanks. Dave. On 4/29/17, Aki Tuomi <aki.tuomi at dovecot.fi> wrote: > >> On April
