Create PKCS7 Signed File (.p7m)

See more Encryption Examples

Demonstrates how to sign a file to create a .p7m that contains both the file contents and the signature. 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 crypt = CkoCrypt2()!

    let certStore = CkoCertStore()!

    // Load a PFX file into a certificate store object.
    success = certStore.loadPfxFile(path: "myPfx.pfx", password: "pfxPassword")
    if success != true {
        print("\(certStore.lastErrorText!)")
        return
    }

    // Get the certificate by subject common name.
    // This should be the cert within the PFX that also
    // has a private key (also stored within the PFX).
    let jsonCN = CkoJsonObject()!
    jsonCN.updateString(jsonPath: "CN", value: "myCert")
    let cert = CkoCert()!
    success = certStore.findCert(json: jsonCN, cert: cert)
    if success == false {
        print("\(certStore.lastErrorText!)")
        return
    }

    // Tell the crypt object to use the certificate for signing:
    success = crypt.setSigningCert(cert: cert)

    // Sign a file, producing a .p7m as output.
    // The input file is unchanged, the test.p7m contains the 
    // contents of the input file and the signature.
    var inFile: String? = "test.txt"
    var outFile: String? = "testp7m"
    success = crypt.createP7M(inPath: inFile, p7mPath: outFile)
    if success != true {
        print("\(crypt.lastErrorText!)")
        return
    }

    print("Success!")
