Encrypt a JWE with a Recipient Public Key

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPublicKey, which sets the public key used to encrypt for a recipient. The example uses RSA-OAEP-256 key management with AES-256-GCM content encryption.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

$jwe = New-Object Chilkat.Jwe

#  Protected header: RSA-OAEP-256 key management with AES-256-GCM content encryption.
$header = New-Object Chilkat.JsonObject
$header.UpdateString("alg","RSA-OAEP-256")
$header.UpdateString("enc","A256GCM")
$success = $jwe.SetProtectedHeader($header)
if ($success -eq $false) {
    $($jwe.LastErrorText)
    exit
}

#  The file path is relative to the application's current working directory.  An absolute path
#  may also be used.  Supply the path appropriate to your own environment.
#  Load the recipient's public key.
$pubKey = New-Object Chilkat.PublicKey
$success = $pubKey.LoadFromFile("qa_data/recipient_pubkey.pem")
if ($success -eq $false) {
    $($pubKey.LastErrorText)
    exit
}

#  Set the public key used to encrypt for recipient 0.
$success = $jwe.SetPublicKey(0,$pubKey)
if ($success -eq $false) {
    $($jwe.LastErrorText)
    exit
}

$jweCompact = $jwe.Encrypt("This is the secret content.","utf-8")
if ($jwe.LastMethodSuccess -eq $false) {
    $($jwe.LastErrorText)
    exit
}
