NAME
hashalot - read a passphrase and print a hashSYNOPSIS
hashalot [ -s SALT ] [ -x ] [ -n #BYTES ] [ -q ] [ HASHTYPE ]HASHTYPE [ -s SALT ] [ -x ] [ -n #BYTES ] [ -q ]
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 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.
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 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 superfluous.
