|
This document specifies algorithm identifiers and ASN.1 encoding formats for the following stateful Hash-Based Signature (HBS) schemes: Hierarchical Signature System (HSS), eXtended MerkleSignature Scheme (XMSS), and XMSS^MT (a multi-tree variant of XMSS).This specification applies to the Internet X.509 Public KeyInfrastructure (PKI) when digital signatures are used to sign certificates and certificate revocation lists (CRLs). |

RFC 9803 | Extensible Provisioning Protocol (EPP) Mapping for DNS Time-to-Live (TTL) Values |
|
|
This document describes an extension to the Extensible ProvisioningProtocol (EPP) that allows EPP clients to manage the Time-to-Live(TTL) value for domain name delegation records. |

RFC 9804 | Simple Public Key Infrastructure (SPKI) S-Expressions |
|
|
This memo specifies the data structure representation that was devised to support Simple Public Key Infrastructure (SPKI) certificates, as detailed in RFC 2692, with the intent that it be more widely applicable. It has been and is being used elsewhere.There are multiple implementations in a variety of programming languages. Uses of this representation are referred to in this document as "S-expressions". This memo makes precise the encodings of these SPKI S-expressions: It gives a "canonical form" for them, describes two "transport" representations, and also describes an"advanced" format for display to people. |

RFC 9805 | Deprecation of the IPv6 Router Alert Option for New Protocols |
|
|
This document deprecates the IPv6 Router Alert option. Protocols that use the IPv6 Router Alert option may continue to do so, even in future versions. However, new protocols that are standardized in the future must not use the IPv6 Router Alert option.
This document updates RFC 2711. |
