System.Security.Cryptography.Pkcs Namespace

 

The System.Security.Cryptography.Pkcs namespace provides programming elements for Public Key Cryptography Standards (PKCS), including methods for signing data, exchanging keys, requesting certificates, public key encryption and decryption, and other security functions.

ClassDescription
System_CAPS_pubclassAlgorithmIdentifier

The AlgorithmIdentifier class defines the algorithm used for a cryptographic operation.

System_CAPS_pubclassCmsRecipient

The CmsRecipient class defines the recipient of a CMS/PKCS #7 message.

System_CAPS_pubclassCmsRecipientCollection

The CmsRecipientCollection class represents a set of CmsRecipient objects. CmsRecipientCollection implements the ICollection interface.

System_CAPS_pubclassCmsRecipientEnumerator

The CmsRecipientEnumerator class provides enumeration functionality for the CmsRecipientCollection collection. CmsRecipientEnumerator implements the IEnumerator interface.

System_CAPS_pubclassCmsSigner

The CmsSigner class provides signing functionality.

System_CAPS_pubclassContentInfo

The ContentInfo class represents the CMS/PKCS #7 ContentInfo data structure as defined in the CMS/PKCS #7 standards document. This data structure is the basis for all CMS/PKCS #7 messages.

System_CAPS_pubclassEnvelopedCms

The EnvelopedCms class represents a CMS/PKCS #7 structure for enveloped data.

System_CAPS_pubclassKeyAgreeRecipientInfo

The KeyAgreeRecipientInfo class defines key agreement recipient information. Key agreement algorithms typically use the Diffie-Hellman key agreement algorithm, in which the two parties that establish a shared cryptographic key both take part in its generation and, by definition, agree on that key. This is in contrast to key transport algorithms, in which one party generates the key unilaterally and sends, or transports it, to the other party.

System_CAPS_pubclassKeyTransRecipientInfo

The KeyTransRecipientInfo class defines key transport recipient information. Key transport algorithms typically use the RSA algorithm, in which an originator establishes a shared cryptographic key with a recipient by generating that key and then transporting it to the recipient. This is in contrast to key agreement algorithms, in which the two parties that will be using a cryptographic key both take part in its generation, thereby mutually agreeing to that key.

System_CAPS_pubclassPkcs9AttributeObject

Represents an attribute used for CMS/PKCS #7 and PKCS #9 operations.

System_CAPS_pubclassPkcs9ContentType

The Pkcs9ContentType class defines the type of the content of a CMS/PKCS #7 message.

System_CAPS_pubclassPkcs9DocumentDescription

The Pkcs9DocumentDescription class defines the description of the content of a CMS/PKCS #7 message.

System_CAPS_pubclassPkcs9DocumentName

The Pkcs9DocumentName class defines the name of a CMS/PKCS #7 message.

System_CAPS_pubclassPkcs9MessageDigest

The Pkcs9MessageDigest class defines the message digest of a CMS/PKCS #7 message.

System_CAPS_pubclassPkcs9SigningTime

The Pkcs9SigningTime class defines the signing date and time of a signature. A Pkcs9SigningTime object can be used as an authenticated attribute of a CmsSigner object when an authenticated date and time are to accompany a digital signature.

System_CAPS_pubclassPublicKeyInfo

The PublicKeyInfo class represents information associated with a public key.

System_CAPS_pubclassRecipientInfo

The RecipientInfo class represents information about a CMS/PKCS #7 message recipient. The RecipientInfo class is an abstract class inherited by the KeyAgreeRecipientInfo and KeyTransRecipientInfo classes.

System_CAPS_pubclassRecipientInfoCollection

The RecipientInfoCollection class represents a collection of RecipientInfo objects. RecipientInfoCollection implements the ICollection interface.

System_CAPS_pubclassRecipientInfoEnumerator

The RecipientInfoEnumerator class provides enumeration functionality for the RecipientInfoCollection collection. RecipientInfoEnumerator implements the IEnumerator interface.

System_CAPS_pubclassSignedCms

The SignedCms class enables signing and verifying of CMS/PKCS #7 messages.

System_CAPS_pubclassSignerInfo

The SignerInfo class represents a signer associated with a SignedCms object that represents a CMS/PKCS #7 message.

System_CAPS_pubclassSignerInfoCollection

The SignerInfoCollection class represents a collection of SignerInfo objects. SignerInfoCollection implements the ICollection interface.

System_CAPS_pubclassSignerInfoEnumerator

The SignerInfoEnumerator class provides enumeration functionality for the SignerInfoCollection collection. SignerInfoEnumerator implements the IEnumerator interface.

System_CAPS_pubclassSubjectIdentifier

The SubjectIdentifier class defines the type of the identifier of a subject, such as a CmsSigner or a CmsRecipient. The subject can be identified by the certificate issuer and serial number or the subject key.

System_CAPS_pubclassSubjectIdentifierOrKey

The SubjectIdentifierOrKey class defines the type of the identifier of a subject, such as a CmsSigner or a CmsRecipient. The subject can be identified by the certificate issuer and serial number, the hash of the subject key, or the subject key.

EnumerationDescription
System_CAPS_pubenumKeyAgreeKeyChoice

The KeyAgreeKeyChoice enumeration defines the type of key used in a key agreement protocol.

System_CAPS_pubenumRecipientInfoType

The RecipientInfoType enumeration defines the types of recipient information.

System_CAPS_pubenumSubjectIdentifierOrKeyType

The SubjectIdentifierOrKeyType enumeration defines how a subject is identified.

System_CAPS_pubenumSubjectIdentifierType

The SubjectIdentifierType enumeration defines the type of subject identifier.
