Convert PFX to JWK Set

See more PFX/P12 Examples

Demonstrates how to convert a PFX (.pfx or .p12) to a JWK Set (a JSON Web Key Set). Objective-C

#import <CkoPfx.h>
#import <NSString.h>
#import <CkoJavaKeyStore.h>
#import <CkoStringBuilder.h>
#import <CkoJsonObject.h>

BOOL success = NO;

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

CkoPfx *pfx = [[CkoPfx alloc] init];

success = [pfx LoadPfxFile: @"qa_data/pfx/myEccCert.p12" password: @"MY_ECC_PFX_PASSWORD"];
if (success == NO) {
    NSLog(@"%@",pfx.LastErrorText);
    return;
}

//  To get the contents of the PFX in JWK Set form, we must first convert
//  to a Java KeyStore object:
//  The alias will become the key id ("kid") the the JWK Set.
//  The password is an input argument that becomes the password for the JavaKeyStore.
NSString *alias = @"my_ecc_key";
NSString *password = @"secret123";
CkoJavaKeyStore *jks = [[CkoJavaKeyStore alloc] init];
success = [pfx ToJksObj: alias password: password jksObj: jks];
if (success == NO) {
    NSLog(@"%@",pfx.LastErrorText);
    return;
}

CkoStringBuilder *sbJwkSet = [[CkoStringBuilder alloc] init];
//  The ToJwkSet method writes to sbJwkSet.
success = [jks ToJwkSet: password sbJwkSet: sbJwkSet];
if (success == NO) {
    NSLog(@"%@",jks.LastErrorText);
    return;
}

CkoJsonObject *jwkSet = [[CkoJsonObject alloc] init];
[jwkSet LoadSb: sbJwkSet];
jwkSet.EmitCompact = NO;

NSLog(@"%@",[jwkSet Emit]);

//  The output is:
//  (Line breaks in the "x5c" base64 data were added for readability)
