PKCS7 Decrypt MIME

See more MIME Examples

Loads a PKCS7 encrypted MIME file and decrypts. The cert and private key used for decryption is loaded from a PFX file. Swift

func chilkatTest() {
    var success: Bool = false

    // This example requires 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: "encryptedMime.txt")
    if success == false {
        print("\(mime.lastErrorText!)")
        return
    }

    // The AddPfxSourceFile and/or AddPfxSourceData
    // methods may be called one or more times (one per PFX)
    // to add sources from which the MIME component will
    // search for certificates and private keys when decrypting.
    var pfxPassword: String? = "myPassword"
    success = mime.addPfxSourceFile(pfxFilePath: "myCertAndPrivateKey.pfx", password: pfxPassword)
    if success == false {
        print("\(mime.lastErrorText!)")
        return
    }

    // Decrypt...
    success = mime.decrypt()
    if success == false {
        print("\(mime.lastErrorText!)")
        return
    }

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