NAME
sntrup - command-line interface for the libntruprime implementation of the Streamlined NTRU Prime cryptosystem
SYNOPSIS
Key generation (for, e.g., sntrup1277
):
sntrup1277-keypair 5>publickey 9>secretkey
Encapsulation (for, e.g., sntrup1277
):
sntrup1277-enc >ciphertext 7>sessionkey 4<publickey
Decapsulation (for, e.g., sntrup1277
):
sntrup1277-dec 7>sessionkey <ciphertext 8<secretkey
DESCRIPTION
libntruprime is an implementation of the Streamlined NTRU Prime cryptosystem. The command-line interface for libntruprime provides the following command-line tools:
sntrup{653,761,857,953,1013,1277}-keypair
sntrup{653,761,857,953,1013,1277}-enc
sntrup{653,761,857,953,1013,1277}-dec
Each tool exits 0 on success, nonzero on failure.
These tools allow libntruprime to be easily used from shell scripts. Other languages can also use libntruprime via these tools, but languages typically have good support for FFI and can use the C interface directly.
The details below use sntrup1277
as an example.
KEY GENERATION
Alice runs the sntrup1277-keypair
command.
This command randomly generates
Alice's secret key and Alice's corresponding public key.
It writes the public key to file descriptor 5,
and then writes the secret key to file descriptor 9.
ENCAPSULATION
Bob runs the sntrup1277-enc
command.
This command
reads Alice's public key from file descriptor 4.
It randomly generates
a ciphertext and the corresponding session key.
It writes the ciphertext to stdout,
and then writes the session key to file descriptor 7.
DECAPSULATION
Alice runs the sntrup1277-dec
command.
This command
reads Alice's secret key from file descriptor 8,
and then reads a ciphertext from stdin.
It computes the corresponding session key,
which it writes to file descriptor 7.
