NAME¶
pkcs15-crypt - perform crypto operations using pkcs15 smart cardSYNOPSIS¶
DESCRIPTION¶
The pkcs15-crypt utility can be used from the command line to perform cryptographic operations such as computing digital signatures or decrypting data, using keys stored on a PKCS #15 compliant smart card.OPTIONS¶
--sign, -sPerform digital signature operation on the
data read from a file specified using the input option. By default, the
contents of the file are assumed to be the result of an MD5 hash operation.
Note that pkcs15-crypt expects the data in binary representation, not
ASCII.
The digital signature is stored, in binary representation, in the file specified
by the output option. If this option is not given, the signature is
printed on standard output, displaying non-printable characters using their
hex notation xNN (see also --raw).
--pkcs1
By default, pkcs15-crypt assumes that
input data has been padded to the correct length (i.e. when computing an RSA
signature using a 1024 bit key, the input must be padded to 128 bytes to match
the modulus length). When giving the --pkcs1 option, however,
pkcs15-crypt will perform the required padding using the algorithm
outlined in the PKCS #1 standard version 1.5.
--sha-1
This option tells pkcs15-crypt that the
input file is the result of an SHA1 hash operation, rather than an MD5 hash.
Again, the data must be in binary representation.
--decipher, -c
Decrypt the contents of the file specified by
the --input option. The result of the decryption operation is written
to the file specified by the --output option. If this option is not
given, the decrypted data is printed to standard output, displaying
non-printable characters using their hex notation xNN (see also
--raw).
--key id, -k id
Selects the ID of the key to use.
--reader N, -r N
Selects the N-th smart card reader
configured by the system. If unspecified, pkcs15-crypt will use the
first reader found.
--input file, -i file
Specifies the input file to use.
--output file, -o file
Any output will be sent to the specified
file.
--raw, -R
Outputs raw 8 bit data.
--pin pin, -p pin
When the cryptographic operation requires a
PIN to access the key, pkcs15-crypt will prompt the user for the PIN on
the terminal. Using this option allows you to specify the PIN on the command
line.
Note that on most operating systems, the command line of a process can be
displayed by any user using the ps(1) command. It is therefore a security risk
to specify secret information such as PINs on the command line. If you specify
'-' as PIN, it will be read from STDIN.
--aid aid
Specify in a hexadecimal form the AID of the
on-card PKCS#15 application to be binded to.
--verbose, -v
Causes pkcs15-crypt to be more verbose.
Specify this flag several times to enable debug output in the OpenSC
library.
