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.

Classes

AlgorithmIdentifier	The AlgorithmIdentifier class defines the algorithm used for a cryptographic operation.
CmsRecipient	The CmsRecipient class defines the recipient of a CMS/PKCS #7 message.
CmsRecipientCollection	The CmsRecipientCollection class represents a set of CmsRecipient objects. CmsRecipientCollection implements the ICollection interface.
CmsRecipientEnumerator	The CmsRecipientEnumerator class provides enumeration functionality for the CmsRecipientCollection collection. CmsRecipientEnumerator implements the IEnumerator interface.
CmsSigner	Represents a potential signer for a CMS/PKCS#7 signed message.
ContentInfo	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.
EnvelopedCms	Represents a CMS/PKCS#7 structure for enveloped data.
KeyAgreeRecipientInfo	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.
KeyTransRecipientInfo	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.
Pkcs12Builder	Enables the creation of PKCS#12 PFX data values. This class cannot be inherited.
Pkcs12CertBag	Represents the PKCS#12 CertBag. This class cannot be inherited.
Pkcs12Info	Represents the data from PKCS#12 PFX contents. This class cannot be inherited.
Pkcs12KeyBag	Represents the KeyBag from PKCS#12, a container whose contents are a PKCS#8 PrivateKeyInfo. This class cannot be inherited.
Pkcs12SafeBag	Defines the core behavior of a SafeBag value from the PKCS#12 specification and provides a base for derived classes.
Pkcs12SafeContents	Represents a PKCS#12 SafeContents value. This class cannot be inherited.
Pkcs12SafeContentsBag	Represents the SafeContentsBag from PKCS#12, a container whose contents are a PKCS#12 SafeContents value. This class cannot be inherited.
Pkcs12SecretBag	Represents the SecretBag from PKCS#12, a container whose contents are arbitrary data with a type identifier. This class cannot be inherited.
Pkcs12ShroudedKeyBag	Represents the ShroudedKeyBag from PKCS#12, a container whose contents are a PKCS#8 EncryptedPrivateKeyInfo. This class cannot be inherited.
Pkcs8PrivateKeyInfo	Enables the inspection of and creation of PKCS#8 PrivateKeyInfo and EncryptedPrivateKeyInfo values. This class cannot be inherited.
Pkcs9AttributeObject	Represents an attribute used for CMS/PKCS #7 and PKCS #9 operations.
Pkcs9ContentType	The Pkcs9ContentType class defines the type of the content of a CMS/PKCS #7 message.
Pkcs9DocumentDescription	The Pkcs9DocumentDescription class defines the description of the content of a CMS/PKCS #7 message.
Pkcs9DocumentName	The Pkcs9DocumentName class defines the name of a CMS/PKCS #7 message.
Pkcs9LocalKeyId	Represents the LocalKeyId attribute from PKCS#9.
Pkcs9MessageDigest	The Pkcs9MessageDigest class defines the message digest of a CMS/PKCS #7 message.
Pkcs9SigningTime	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.
PublicKeyInfo	The PublicKeyInfo class represents information associated with a public key.
RecipientInfo	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.
RecipientInfoCollection	The RecipientInfoCollection class represents a collection of RecipientInfo objects. RecipientInfoCollection implements the ICollection interface.
RecipientInfoEnumerator	The RecipientInfoEnumerator class provides enumeration functionality for the RecipientInfoCollection collection. RecipientInfoEnumerator implements the IEnumerator interface.
Rfc3161TimestampRequest	Represents a time-stamping request from IETF RFC 3161.
Rfc3161TimestampToken	Represents a time-stamp token from IETF RFC 3161.
Rfc3161TimestampTokenInfo	Represents the timestamp token information class defined in RFC3161 as TSTInfo.
SignedCms	The SignedCms class enables signing and verifying of CMS/PKCS #7 messages.
SignerInfo	The SignerInfo class represents a signer associated with a SignedCms object that represents a CMS/PKCS #7 message.
SignerInfoCollection	The SignerInfoCollection class represents a collection of SignerInfo objects. SignerInfoCollection implements the ICollection interface.
SignerInfoEnumerator	The SignerInfoEnumerator class provides enumeration functionality for the SignerInfoCollection collection. SignerInfoEnumerator implements the IEnumerator interface.
SubjectIdentifier	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.
SubjectIdentifierOrKey	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.

Enums

Pkcs12ConfidentialityMode	Represents the kind of encryption associated with a PKCS#12 SafeContents value.
Pkcs12IntegrityMode	Represents the type of anti-tampering applied to a PKCS#12 PFX value.
RecipientInfoType	The RecipientInfoType enumeration defines the types of recipient information.
SubjectIdentifierOrKeyType	The SubjectIdentifierOrKeyType enumeration defines how a subject is identified.
SubjectIdentifierType	The SubjectIdentifierType enumeration defines the type of subject identifier.
