Can blowfish encryption be used as the password hashing algorithm in Red Hat Enterprise Linux?

Solution Unverified - Updated -

Issue

  • I would like to migrate a blowfish encrypted /etc/passwd from another distribution to RHEL. Is this possible?

  • NIS server algorithm is changed from MD5 to blowfish on the NIS Server. NIS server is not RHEL. Now, RHEL NIS client is not able to authenticate via blowfish algorithm.

  • Can we enable BlowFish instead of MD5 in RHEL 5?
