S/MIME provides a consistent way to send and receive secure MIME data. Digital signatures provide authentication, message integrity, and non-repudiation with proof of origin. Encryption provides data confidentiality. Compression can be used to reduce data size. This document obsoletes RFC 5751.
RFC8649 - Hash Of Root Key Certificate Extension: This document specifies the Hash Of Root Key certificate extension. This certificate extension is carried in the self-signed certificate for a trust anchor, which is often called a Root Certification Authority (CA) certificate. This certificate extension unambiguously identifies the next public key that will be used at some point in the future as the next Root CA certificate, eventually replacing the current one.
RFC8659 - DNS Certification Authority Authorization (CAA) Resource Record: The Certification Authority Authorization (CAA) DNS Resource Record allows a DNS domain name holder to specify one or more Certification Authorities (CAs) authorized to issue certificates for that domain name.

This document updates the "Algorithms and Identifiers for the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile" (RFC 3279) and describes the conventions for using the SHAKE function family in Internet X.509 certificates and revocation lists as one-way hash functions with the RSA Probabilistic signature and Elliptic Curve Digital Signature Algorithm (ECDSA) signature algorithms. The conventions for the associated subject public keys are also described.
RFC8696 - Using Pre-Shared Key (PSK) in the Cryptographic Message Syntax (CMS): The invention of a large-scale quantum computer would pose a serious challenge for the cryptographic algorithms that are widely deployed today. The Cryptographic Message Syntax (CMS) supports key transport and key agreement algorithms that could be broken by the invention of such a quantum computer. By storing communications that are protected with the CMS today, someone could decrypt them in the future when a large-scale quantum computer becomes available. Once quantum-secure key management algorithms are available, the CMS will be extended to support the new algorithms if the existing syntax does not accommodate them. This document describes a mechanism to protect today's communication from the future invention of a large-scale quantum computer by mixing the output of key transport and key agreement algorithms with a pre-shared key.

The conventions for the associated signer public keys in CMS are also described.
RFC8708 - Use of the HSS/LMS Hash-Based Signature Algorithm in the Cryptographic Message Syntax (CMS): This document specifies the conventions for using the Hierarchical Signature System (HSS) / Leighton-Micali Signature (LMS) hash-based signature algorithm with the Cryptographic Message Syntax (CMS). In addition, the algorithm identifier and public key syntax are provided. The HSS/LMS algorithm is one form of hash-based digital signature; it is described in RFC 8554.

RFC8933 - Update to the Cryptographic Message Syntax (CMS) for Algorithm Identifier Protection: This document updates the Cryptographic Message Syntax (CMS) specified in RFC 5652 to ensure that algorithm identifiers in signed-data and authenticated-data content types are adequately protected.
RFC8951 - Clarification of Enrollment over Secure Transport (EST): Transfer Encodings and ASN.1: This document updates RFC 7030: Enrollment over Secure Transport to resolve some errata that were reported and that have proven to cause interoperability issues when RFC 7030 was extended.; This document deprecates the specification of "Content-Transfer-Encoding" headers for Enrollment over Secure Transport (EST) endpoints. This document fixes some syntactical errors in ASN.1 that were present.
RFC8954 - Online Certificate Status Protocol (OCSP) Nonce Extension: This document specifies the updated format of the Nonce extension in the Online Certificate Status Protocol (OCSP) request and response messages. OCSP is used to check the status of a certificate, and the Nonce extension is used to cryptographically bind an OCSP response message to a particular OCSP request message. This document updates RFC 6960.
RFC9044 - Using the AES-GMAC Algorithm with the Cryptographic Message Syntax (CMS): This document specifies the conventions for using the AES-GMAC Message Authentication Code algorithm with the Cryptographic Message Syntax (CMS) as specified in RFC 5652.

RFC9158 - Update to the Object Identifier Registry for the PKIX Working Group: RFC 7299 describes the object identifiers that were assigned by the Public Key Infrastructure using X.509 (PKIX) Working Group in an arc that was allocated by IANA (1.3.6.1.5.5.7). A small number of object identifiers that were assigned in RFC 4212 are omitted from RFC 7299, and this document updates RFC 7299 to correct that oversight.
RFC9216 - S/MIME Example Keys and Certificates: The S/MIME development community benefits from sharing samples of signed or encrypted data. This document facilitates such collaboration by defining a small set of X.509v3 certificates and keys for use when generating such samples.

This document updates RFCs 4210, 5912, and 6712.; The aspects of CMP updated in this document are using EnvelopedData instead of EncryptedValue, clarifying the handling of p10cr messages, improving the crypto agility, as well as adding new general message types, extended key usages to identify certificates for use with CMP, and well-known URI path segments.; CMP version 3 is introduced to enable signaling support of EnvelopedData instead of EncryptedValue and signal the use of an explicit hash AlgorithmIdentifier in certConf messages, as far as needed.
RFC9481 - Certificate Management Protocol (CMP) Algorithms: This document describes the conventions for using several; cryptographic algorithms with the Certificate Management Protocol; (CMP). CMP is used to enroll and further manage the lifecycle of; X.509 certificates. This document also updates the algorithm use; profile from Appendix D.2 of RFC 4210.
RFC9483 - Lightweight Certificate Management Protocol (CMP) Profile: This document aims at simple, interoperable, and automated PKI management operations covering typical use cases of industrial and Internet of Things (IoT) scenarios. This is achieved by profiling the Certificate Management Protocol (CMP), the related Certificate Request Message Format (CRMF), and transfer based on HTTP or Constrained Application Protocol (CoAP) in a succinct but sufficiently detailed and self-contained way. To make secure certificate management for simple scenarios and constrained devices as lightweight as possible, only the most crucial types of operations and options are specified as mandatory. More specialized or complex use cases are supported with optional features.
RFC9495 - Certification Authority Authorization (CAA) Processing for Email Addresses: The Certification Authority Authorization (CAA) DNS resource record (RR) provides a mechanism for domains to express the allowed set of Certification Authorities that are authorized to issue certificates for the domain. RFC 8659 contains the core CAA specification, where Property Tags that restrict the issuance of certificates that certify domain names are defined. This specification defines a Property Tag that grants authorization to Certification Authorities to issue certificates that contain the key purpose in the extension and at least one value or value of type that includes the domain name in the extension.
RFC9509 - X.509 Certificate Extended Key Usage (EKU) for 5G Network Functions: RFC 5280 specifies several extended key purpose identifiers (KeyPurposeIds) for X.509 certificates.
