Hello guys,
I'm currently working on replacing old server and it's migration from SuSe

Code:

SUSE Linux Enterprise Server 10 (x86_64)
VERSION = 10
PATCHLEVEL = 4

to the RedHat

Code:

Red Hat Enterprise Linux Server release 6.4 (Santiago)

Problem seems be in migration of users passwords, respectively in password encryption.

On SuSe is used des encryption

Code:

cat /etc/default/passwd | grep CRYPT
CRYPT=des

but in /etc/shadow I see:

Code:

user1:$1$gDXlJQcH$1Z5otL/07nPZJtF8VVaGY0:15552:1:93:7:::
user2:$2a$04$Osw2KnOXMJjDvYuvtoJAked1cnjXBF3RRpJhqmi21.C1nQrQ89jNi:15580::::::

So it looks that some from passwords are encrypted with MD5, and some of them with Blowfish. Is my suggestion right??

While RedHat is using SHA512

Code:

cat /etc/login.defs | grep CRYP
ENCRYPT_METHOD SHA512
MD5_CRYPT_ENAB no

I would like ask if is possible to convert current passwords from MD5 and Blowfish to the SHA512 and use them directly on new RedHat server??


Many thanks for hints.
