GCIPHER(1) GNOME GCIPHER(1)NAME
gcipher - a simple encryption tool
SYNOPSIS
gcipher
gcipher [CIPHEROPTIONS]... [INPUT] [OUTPUT]
gcipher [CIPHEROPTIONS]... -p PROXIEDHOST PROXIEDPORT LISTENINGPORT
CIPHEROPTIONS:
(-c | -C) CIPHER [-k KEY]
"-" may be used for either INPUT or OUTPUT to represent STDIN or STDOUT respectively.
EXAMPLES
Show the GUI:
gcipher
Encrypt a file using the Gie cipher:
gcipher -c Gie inputfile outputfile
Decrypt STDIN and output to STDOUT using Rot13:
gcipher -C Rot -k 13
Listen on port 1027 and act as a proxy for port 1028 on gnu.org. Decrypt the data coming from gnu.org and encrypt data going to gnu.org
using Vigenere with key linux:
gcipher -c Vigenere -k linux -p gnu.org 1028 1027
DESCRIPTION
This is a simple encryption tool to work with home-grown encryption algorithms. It can run as either a GUI, a command-line application, or
a network proxy.
-c CIPHER
encrypt using the given cipher
-C CIPHER
decrypt using the given cipher
-k KEY set the key for the previous cipher
-p PROXIEDHOST PROXIEDPORT LISTENINGPORT
act as a network proxy
CIPHERS
Gie a simple cipher doable by hand; no key is required
Caesar Julius Caesar's code; no key is required
Rot linear rotation; the amount of the rotation is given by the key which must be a number in the range [0, 25]
Vigenere
a version of ROT that uses a private key; the key must be made of lower-case letters

gnutls_x509_privkey_export2_pkcs8 - API function
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_privkey_export2_pkcs8(gnutls_x509_privkey_t key, gnutls_x509_crt_fmt_t format, const char * password, unsigned int flags,
gnutls_datum_t * out);
ARGUMENTS
gnutls_x509_privkey_t key
Holds the key
gnutls_x509_crt_fmt_t format
the format of output params. One of PEM or DER.
const char * password
the password that will be used to encrypt the key.
unsigned int flags
an ORed sequence of gnutls_pkcs_encrypt_flags_t
gnutls_datum_t * out
will contain a private key PEM or DER encoded
DESCRIPTION
This function will export the private key to a PKCS8 structure. Both RSA and DSA keys can be exported. For DSA keys we use PKCS 11 defini-
tions. If the flags do not specify the encryption cipher, then the default 3DES (PBES2) will be used.
The password can be either ASCII or UTF-8 in the default PBES2 encryption schemas, or ASCII for the PKCS12 schemas.
The output buffer is allocated using gnutls_malloc().
If the structure is PEM encoded, it will have a header of "BEGIN ENCRYPTED PRIVATE KEY" or "BEGIN PRIVATE KEY" if encryption is not used.
RETURNS
In case of failure a negative error code will be returned, and 0 on success.
Since 3.1.3
