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
