(0)

A password often needs to be convert to an MD5 or SHA algorithm using OpenSSL to be paste as hash into a SQL table or into a configuration file such as an XML or JSON file.

This is where the OpenSSL Toolkit can be used to convert a password.

Message-Digest Algorithm 5 (MD5) is a popular cryptographic hash function that calculates a 128-bit hash value from any message. Secure Hash Algorithm (SHA) refers to a group of standardized cryptological hash functions and is used to calculate a check value for any digital data and is, among other things, the basis for creating a digital signature.

How to convert a password to MD5-based or SHA algorithm hash with OpenSSL

How to convert password MD5-based

Fire up an terminal shell (Ctrl+Alt+T) or an command prompt and hitopenssl passwdto convert a password to MD5-based algorithm.

openssl passwd -1 "TopSecret"
$1$UwcEHfFx$pv99SO2tq3MZ5u2JtTN.O0

A password is converted to SHA256-based algorithm.

openssl passwd -5 "TopSecret"
$5$6wC.6bysAZzl1zAm$758mNsbX6d.Uzhrm1eAtF3ftrWBgnYi/BES8tSYgKR1

The option password displaying the hash together with text to digest.

openssl passwd -5 password "TopSecret"
$5$6wC.6bysAZzl1zAm$758mNsbX6d.Uzhrm1eAtF3ftrWBgnYi/BES8tSYgKR1
$5$Po.hbT1imQPmydXm$seJP5igIfO0NmTLfx6IcBxrgU7Hh2HthpJ9VTqWWag9

This input convert to SHA512-based password algorithm.

openssl passwd -6 "TopSecret"
$6$CRY0sZkUObU1tIMg$JFM8Artzxz6efj3kVTMyfXimOD.cSZB3VAh3a7pShjJBLiiU598D0YCKCsyBaOXvhwiJG7Onf4Djru2XjMBKf.

This input convert MD5-based password Apache variant algorithm using OpenSSL.

openssl passwd -apr1 "TopSecret"
$apr1$cVLBkacR$hKouNKpKP0XUkOoNfsPBx/

 openssl is also available for windows, the article here shows how to do it.
