.SH NAME
bindfile \- encrypts a data file
.SH SYNOPSIS

bindfile <public key file> <input file> <outputfile>

     
.SH DESCRIPTION
This command will encrypt a small file.
.SH ARGUMENTS
.TP 5
public key file
this is the full file path, name, and extension for the public
key that is to be used for encrypting the file.  It usually has a file
extension of ".pem".
.TP 5
input file
is the name of the file containing the data to be encrypted.
The file to encrypt cannot be longer than the maximum block size which can be
encrypted by the specified RSA key. For RSA keys with a modulus 2048 bits
in length, this maximum is approximately 245 bytes.
The bindfile program is therefore usually used to encrypt
short items, such as other keys or passwords.
.TP 5
output file
This specifies the name of the output file, which contains the encrypted data.
