## Encrypt > [!NOTE] Do not apply transformations to your message’s payload when performing cryptographic > operations. Transform operations don’t exclude cryptographic signatures. This example shows you how to apply encryption using a keystore: Encryption Example ```XML ``` ## Sign > [!NOTE] Do not apply transformations to your message’s payload when performing cryptographic > operations. Transform operations don’t exclude cryptographic signatures. This example shows you how to sign a SOAP response using a keystore and the `RSAwithSHA256` algorithm: Signature Example ```XML ``` ## Encrypt and Sign a Certificate > [!NOTE] Do not apply transformations to your message’s payload when performing cryptographic > operations. Transform operations don’t exclude cryptographic signatures. This example validates a signed request, saves the signing certificate, and uses it later in the `apply-wss` operation to sign the response: Request Example ```XML yLFLEkH4/MjYbZ4viZxjou9/4os=xxxxx+xxxxxxxxx==CN=Unknown,OU=Unknown,O=Unknown,L=Unknown,ST=Unknown,C=US1545521240 test ``` Encryption Example ```XML ```
