Hashing password with bcrypt in Solaris 10. Alternative from Oracle?
Hi,
Our security audit person generated a report for Solaris-10 servers and mentioned this suggestion - "All passwords should be hashed using bcrypt. Solaris 10 supports this blowfish-based hash algorithm with the identifier 2a. To verify this, ensure the password hashes start with $2a$. Additionally, all passwords currently hashed as descrypt should be changed."
Looks like, it is a third party utility and not from Oracle. In case of any issue, they may say that it is not supported by us. For achieving similar result, does Solaris have any default tool instead of testing/implementing a third party tool ?
Please advice.
Thanks

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)
Thanks,

hashalot
HASHALOT(1) General Commands Manual HASHALOT(1)
NAME
hashalot - read a passphrase and print a hash
SYNOPSIS
hashalot [ -t secs ] [ -s SALT ] [ -x ] [ -n #BYTES ] [ -C itercountk ] HASHTYPE
HASHTYPE [ -t secs ] [ -s SALT ] [ -x ] [ -n #BYTES ] [ -C itercountk ]
DESCRIPTION
hashalot is a small tool that reads a passphrase from standard input, hashes it using the given hash type, and prints the result to stan-
dard output.
Supported values for HASHTYPE:
ripemd160 rmd160 rmd160compat sha256 sha384 sha512
OPTIONS
The option -s SALT specifies an initialization vector to the hashing algorithm. You need this if you want to prevent identical passwords to
map to identical hashes, which is a security risk.
If the -x option is given then the hash will be printed as a string of hexadecimal digits.
The -n option can be used to limit (or increase) the number of bytes output. The default is as appropriate for the specified hash algo-
rithm: 20 bytes for RIPEMD160, 32 bytes for SHA256, etc. The default for the "rmd160compat" hash is 16 bytes, for compatibility with the
old kerneli.org utilities.
The -t option specifies a timeout for reading the passphrase from the terminal.
The -C option specifies that the hashed password has to be encrypted itercountk thousand times using AES-256. Use for compatability with
loop-AES.
The options -t and -C are currently SUSE specific
