PROGRAM:

NAME


scrypt — encrypt and decrypt files.

SYNOPSIS


scrypt {enc | dec} [-M maxmem] [-m maxmemfrac] [-t maxtime] infile [outfile]

DESCRIPTION


scrypt enc encrypts infile and writes the result to outfile if specified, or the standard
output otherwise. The user will be prompted to enter a passphrase (twice) to be used to
generate a derived encryption key.

scrypt dec decrypts infile and writes the result to outfile if specified, or the standard
output otherwise. The user will be prompted to enter the passphrase used at encryption time
to generate the derived encryption key.

OPTIONS


-M maxmem Use at most maxmem bytes of RAM to compute the derived encryption key.

-m maxmemfrac Use at most the fraction maxmemfrac of the available RAM to compute the
derived encryption key.

-t maxtime Use at most maxtime seconds of CPU time to compute the derived encryption
key.

In scrypt enc, the memory and CPU time limits are enforced by picking appropriate parameters
to the scrypt key derivation function. In scrypt dec, the memory and CPU time limits are
enforced by exiting with an error if decrypting the file would require too much memory or
CPU time.

EXIT STATUS


The scrypt utility exits 0 on success, and >0 if an error occurs.

Note that if the input encrypted file is corrupted, scrypt dec may produce output prior to
determining that the input was corrupt and exiting with a non-zero status; so users should
direct the output to a safe location and check the exit status of scrypt before using the
decrypted data.
