HASHALOT(1)HASHALOT(1)NAMEhashalot - read a passphrase and print a hash
SYNOPSIShashalot [ -t secs ] [ -s SALT ] [ -x ] [ -n #BYTES ] [ -C itercountk ]
HASHTYPE
HASHTYPE [ -t secs ] [ -s SALT ] [ -x ] [ -n #BYTES ] [ -C itercountk ]
DESCRIPTIONhashalot 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.
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 ker‐
neli.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
