NAME¶
pkcs15-crypt - perform crypto operations using PKCS#15 smart cardsSYNOPSIS¶
pkcs15-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 aidSpecify 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 x NN (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.
