Decrypt a .p7m File (using a PFX)

See more Encryption Examples

_LANGUAGE_ sample code showing how to decrypt a .p7m using a .p12 / .pfx certificate w/ private key. Go

    success := false

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

    crypt := chilkat.NewCrypt2()

    // Use a digital certificate and private key from a PFX file (.pfx or .p12).
    pfxPath := "myCertAndKey.pfx"
    pfxPassword := "test123"

    success = crypt.AddPfxSourceFile(pfxPath,pfxPassword)
    if success != true {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        return
    }

    // Set the  outPath to whatever is appropriate.
    // If you are decrypting a PDF, your output might be "out.pdf"...
    inPath := "smime.p7m"
    outPath := "original.txt"

    // Indicate that we're doing public key decryption (i.e. PKCS7)
    crypt.SetCryptAlgorithm("pki")

    success = crypt.CkDecryptFile(inPath,outPath)
    if success == false {
        fmt.Println(crypt.LastErrorText())
        crypt.DisposeCrypt2()
        return
    }

    fmt.Println("Success.")

    crypt.DisposeCrypt2()
