Using System.Security.Cryptography.Pkcs

You can use System.Security.Cryptography.Pkcs to program cryptography into your application. This namespace implements the Cryptographic Message Syntax standard and PKCS #7. Using this standard, you can implement signed messages, enveloped messages, or signed and enveloped messages.

In This Section

The following topics provide information about System.Security.Cryptography.Pkcs namespace.

• How to: Sign Messages by One Signer
  Creates a CMS/PKCS #7 signed message. The message is signed by a single signer.

• How to: Sign a Message by Multiple Signers
  Creates a CMS/PKCS #7 signed message. The message is signed by multiple signers.

• How to: Countersign a Message
  Creates a CMS/PKCS #7 signed message. The message is signed by a single signer. That signature is then countersigned by two other signers.

• How to: Envelope a Message for One Recipient
  Creates a CMS/PKCS #7 enveloped message. The message is encrypted for a single recipient.

• How to: Envelope a Message for Multiple Recipients
  Creates a CMS/PKCS #7 enveloped message. The message is encrypted for multiple recipients.

• How to: Sign and Envelop a Message
  Creates a CMS/PKCS #7 enveloped signed message. The message is first signed by a single signer and is then encrypted for a single recipient.

• Supporting Tasks for Using System.Security.Cryptography.Pkcs
  Contains additional programming tasks.
