PKCS7 Decrypt Using .pfx or .p12 Data

See more MIME Examples

Demonstrates how to decrypt MIME using a specifc PFX file (.pfx or .p12) for the source of certificate(s) and private key(s). Swift

func chilkatTest() {
    var success: Bool = false

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

    let mime = CkoMime()!

    // Load the MIME
    success = mime.loadFile(path: "encrypted.mim")
    if success == false {
        print("\(mime.lastErrorText!)")
        return
    }

    var pfxData: NSData
    let fac = CkoFileAccess()!
    pfxData = fac.readEntireFile(path: "pfxStore/myPkcs12.p12")
    if fac.lastMethodSuccess != true {
        print("\(fac.lastErrorText!)")
        return
    }

    var pfxPassword: String? = "myPassword"
    success = mime.decrypt(usingPfxData: pfxData, password: pfxPassword)
    if success == false {
        print("\(mime.lastErrorText!)")
        return
    }

    // Display the decrypted MIME:
    print("\(mime.getMime()!)")

    // Note: The MIME to be decrypted should look something like this
    // when viewed in a text editor:
    // (Note that the Content-Type is application/x-pkcs7-mime)

    // Content-Disposition: attachment; filename="smime.p7m"
    // Content-Transfer-Encoding: base64
    // Content-Type: application/x-pkcs7-mime;
