Crate rasn_cms

Expand description

§Cryptographic Message Syntax

rasn-cms is an implementation of the data types defined in IETF RFC 4108, RFC 5083, RFC 5084, and RFC 5652. Also known as Cryptographic Message Syntax (CMS) or PKCS#7.

This does not provide an implementation of a CMS generator or validator, instead rasn-cms provides an implementation of the underlying data types used to decode and encode the CMS structures from/to DER or BER.

Modules§

algorithms: Algorithms used with CMS.
authenticode: Windows Authenticode Portable Executable Signature Format
firmware_wrapper: Firmware Package Wrappers
pkcs7_compat: PKCS7 compatibility module.

Structs§

AlgorithmIdentifier: Identifies what algorithm was used, along with any parameters used as input.
Attribute
AuthEnvelopedData
AuthenticatedData: AuthenticatedData represents an authenticated-data content type
Certificate: An X.509 certificate
CertificateList: A signed list of revoked certificates.
ContentInfo: ContentInfo encapsulates a single identified content type, and the identified type may provide further encapsulation.
DigestedData: DigestedData represents a digested-data content type
EncapsulatedContentInfo: The content is represented in the type EncapsulatedContentInfo
EncryptedContentInfo: EncryptedContentInfo is the encrypted content information
EncryptedData: EncryptedData represents an encrypted-data content type
EnvelopedData: EnvelopedData represents an enveloped-data content type
ExtendedCertificate
ExtendedCertificateInfo
IssuerAndSerialNumber: The IssuerAndSerialNumber type identifies a certificate, and thereby an entity and a public key, by the distinguished name of the certificate issuer and an issuer-specific certificate serial number.
KekIdentifier: KekIdentifier specifies a symmetric key-encryption key that was previously distributed to the sender and one or more recipients.
KekRecipientInfo: Recipient information using previously distributed symmetric keys is represented in the type KEKRecipientInfo.
KeyAgreeRecipientInfo: Recipient information using key agreement is represented in the type KeyAgreeRecipientInfo.
KeyTransRecipientInfo: Per-recipient information using key transport is represented in the type KeyTransRecipientInfo. Each instance of KeyTransRecipientInfo transfers the content-encryption key to one recipient.
OriginatorInfo: OriginatorInfo optionally provides information about the originator. It is present only if required by the key management algorithm.
OriginatorPublicKey: The OriginatorPublicKey alternative includes the algorithm identifier and sender’s key agreement public key.
OtherCertificateFormat: OtherCertificateFormat represents a custom certificate format
OtherKeyAttribute: Additional information used by the recipient to determine the key-encryption key used by the sender.
OtherRecipientInfo: Recipient information for additional key management techniques are represented in the type OtherRecipientInfo.
OtherRevocationInfoFormat: The OtherRevocationInfoFormat alternative is provided to support any other revocation information format without further modifications to the CMS.
PasswordRecipientInfo: Recipient information using a password or shared secret value is represented in the type PasswordRecipientInfo.
RecipientEncryptedKey: RecipientEncryptedKey includes a recipient identifier and encrypted key for one or more recipients.
RecipientKeyIdentifier: RecipientKeyIdentifier identifies the recipient’s key.
SignedData: SignedData represents a signed-data content type
SignerInfo: Per-signer information is represented in the type SignerInfo

Enums§

CertificateChoices: The `CertificateChoices`` type contains options for certificate formats.
ExtendedCertificateOrCertificate
KeyAgreeRecipientIdentifier: KeyAgreeRecipientIdentifier is a CHOICE with two alternatives.
Name
OriginatorIdentifierOrKey: OriginatorIdentifierOrKey is a CHOICE with three alternatives specifying the sender’s key agreement public key.
RecipientIdentifier: RecipientIdentifier specifies the recipient’s certificate or key that was used by the sender to protect the content-encryption key.
RecipientInfo: RecipientInfo is a per-recipient information.
RevocationInfoChoice: The RevocationInfoChoice type gives a revocation status information alternatives.
SignerIdentifier: SignerIdentifier data type represents the choice of signer identifications
