PKCS15-CRYPT(1) OpenSC Tools PKCS15-CRYPT(1)NAMEpkcs15-crypt - perform crypto operations using PKCS#15 smart cards
SYNOPSISpkcs15-crypt [OPTIONS]
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--aid aid
Specify the AID of the on-card PKCS#15 application to bind to. The
aid must be in hexadecimal form.
--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).
--input file, -i file
Specifies the input file to use.
--key id, -k id
Selects the ID of the key to use.
--output file, -o file
Any output will be sent to the specified file.
--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.
--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.
--raw, -R
Outputs raw 8 bit data.
--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.
--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.
--sign, -s
Perform 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).
--verbose, -v
Causes pkcs15-crypt to be more verbose. Specify this flag several
times to enable debug output in the OpenSC library.
