Here are some more, Default on RHEL6 is SHA512
md5 - when a user changes their password next, encrypt it with the md5 algorithm.
sha256 - when a user changes their password next, encrypt it with the sha256 algorithm.
sha512 - when a user changes their password next, encrypt it with the sha512 algorithm.
bigcrypt - when a user changes their password next, excrypt it with the DEC C2 - algorithm(0).
If you need to change this in rhel then use /etc/sysconfig/system-auth, be carefull

Hi,
how can one find that which encryption algorithm the system is using for keeping the user password in the /etc/passwd or /etc/shadow file.
Is it
1: Hashing ( which considers only first 5 letters of password)
2: MD5 (Which allows arbitry length passwords)
