hashalot - read a passphrase and print a hash


hashalot [ -s SALT ] [ -x ] [ -n #BYTES ] [ -q ] [ HASHTYPE ]
HASHTYPE [ -s SALT ] [ -x ] [ -n #BYTES ] [ -q ]


hashalot is a small tool that reads a passphrase from standard input, hashes it using the
given hash type, and prints the result to standard output.

Warning: If you do not use the -x option, the hash is printed in binary. This may wedge
your terminal settings, or even force you to log out.

This is not a general purpose hasher, only the first line is used, not even including the
final newline. Thus, don't be surprised if the output seems to be different from other
tools -- you'd have to hash exactly the same string.

Supported values for HASHTYPE:
ripemd160 rmd160 rmd160compat sha256 sha384 sha512


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 algorithm: 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 -q option causes hashalot to be more quiet and not print some warnings which may be
