=head1 NAME
|
|
|
|
PKCS12_newpass - change the password of a PKCS12 structure
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/pkcs12.h>
|
|
|
|
int PKCS12_newpass(PKCS12 *p12, const char *oldpass, const char *newpass);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
PKCS12_newpass() changes the password of a PKCS12 structure.
|
|
|
|
B<p12> is a pointer to a PKCS12 structure. B<oldpass> is the existing password
|
|
and B<newpass> is the new password.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
PKCS12_newpass() returns 1 on success or 0 on failure. Applications can
|
|
retrieve the most recent error from PKCS12_newpass() with ERR_get_error().
|
|
|
|
=head1 EXAMPLE
|
|
|
|
This example loads a PKCS#12 file, changes its password and writes out
|
|
the result to a new file.
|
|
|
|
#include <stdio.h>
|
|
#include <stdlib.h>
|
|
#include <openssl/pem.h>
|
|
#include <openssl/err.h>
|
|
#include <openssl/pkcs12.h>
|
|
|
|
int main(int argc, char **argv)
|
|
{
|
|
FILE *fp;
|
|
PKCS12 *p12;
|
|
if (argc != 5) {
|
|
fprintf(stderr, "Usage: pkread p12file password newpass opfile\n");
|
|
return 1;
|
|
}
|
|
if ((fp = fopen(argv[1], "rb")) == NULL) {
|
|
fprintf(stderr, "Error opening file %s\n", argv[1]);
|
|
return 1;
|
|
}
|
|
p12 = d2i_PKCS12_fp(fp, NULL);
|
|
fclose(fp);
|
|
if (p12 == NULL) {
|
|
fprintf(stderr, "Error reading PKCS#12 file\n");
|
|
ERR_print_errors_fp(stderr);
|
|
return 1;
|
|
}
|
|
if (PKCS12_newpass(p12, argv[2], argv[3]) == 0) {
|
|
fprintf(stderr, "Error changing password\n");
|
|
ERR_print_errors_fp(stderr);
|
|
PKCS12_free(p12);
|
|
return 1;
|
|
}
|
|
if ((fp = fopen(argv[4], "wb")) == NULL) {
|
|
fprintf(stderr, "Error opening file %s\n", argv[4]);
|
|
PKCS12_free(p12);
|
|
return 1;
|
|
}
|
|
i2d_PKCS12_fp(fp, p12);
|
|
PKCS12_free(p12);
|
|
fclose(fp);
|
|
return 0;
|
|
}
|
|
|
|
|
|
=head1 NOTES
|
|
|
|
If the PKCS#12 structure does not have a password, then you must use the empty
|
|
string "" for B<oldpass>. Using NULL for B<oldpass> will result in a
|
|
PKCS12_newpass() failure.
|
|
|
|
If the wrong password is used for B<oldpass> then the function will fail,
|
|
with a MAC verification error. In rare cases the PKCS12 structure does not
|
|
contain a MAC: in this case it will usually fail with a decryption padding
|
|
error.
|
|
|
|
=head1 BUGS
|
|
|
|
The password format is a NULL terminated ASCII string which is converted to
|
|
Unicode form internally. As a result some passwords cannot be supplied to
|
|
this function.
