Convert PEM to JKS (Java KeyStore)

See more PEM Examples

Converts a PEM containing private key(s) and certificates into a JKS (Java KeyStore) formatted file. Objective-C

BOOL success = NO;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoPem *pem = [[CkoPem alloc] init];

// Load the PEM from a file.
// If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
NSString *password = @"myPassword";

// by calling LoadPem instead.

// Check for success as before..

// Convert to a JavaKeyStore object.
// The alias, if a non-empty string, will be applied to the 1st private key or 
// certificate.  All other keys and/or certificates will be assigned an auto-generated
// alias.

// entire JKS file.  This may be different (if desired) than the password for individual private keys
// contained within the JKS.
