Howto convert base64 to md5


Hi, all
I have a LDAP database on Redhat 8.x. When I use ldapsearch comand, I receive userPassword at base64 hash format (userPassword:: e0NSWVBUfSQxJEZ1dVR0cGt0JFd0RkM1eUpOeTd2bmQ1cXNzY3ZMTC8=). Now, I want to convert this hash to MD5 hash. After, I will enter this MD5 hash to /etc/shadow and convert /etc/passwd to ldif file.
Do you have any solutions for this?

Thanks.

You can use openssl to decode the base64 and the pipe it to md5sum like so

Code:
openssl enc -d -base64 -in myb64passwd.txt | md5sum
Depending on the format of your password file you'll probably have to wrap it in some sort of loop to process each password with md5sum individually.

howto convert base64 to md5.

Thanks for regarding.
I have just tried your solution but I can't use hash which export from openssl command.
It displays result:
[root@abc ~]# openssl enc -d -base64 -in myb64passwd.txt | md5sum

Please give me more information.

Thanks.

Yeah, that's md5sum giving you the answer. Look at the man pages for openssl and for md5sum.
