Hello OpenSSL Team,
I did write function which changes PKCS12 passphrase. I noticed that PKCS12_newpass function leaks memory. Memory leak disappears when commenting out line where is PKCS12_newpass func.
Below I posted this code which I am using.
I am using OpneSSL 1.0.2g version.
Could you please give me information what I am doing wrong? Or it is known issue?
Bets regards,
Ramunas
- (NSData*)changePKCS12:(NSData*)p12Data
oldPassphrase:(NSString*)oldPassphrase
newPassphrase:(NSString*)newPassphrase {
OpenSSL_add_all_algorithms();
BIO *bp = NULL;
PKCS12 *p12 = NULL;
int status = 0;
do {
bp = BIO_new_mem_buf((void *)[p12Data bytes], (int)[p12Data length]);
p12 = d2i_PKCS12_bio(bp, NULL);
// MEMORY LEAK in PKCS12_newpass
status = PKCS12_newpass(p12, (char *)[oldPassphrase UTF8String], (char *)[newPassphrase UTF8String]);
} while (false);
if (p12) {
PKCS12_free(p12);
p12 = NULL;
}
if (bp) {
BIO_free_all(bp);
bp = NULL;
}
EVP_cleanup();
return NULL;
}
