TLS ClientCertificateType Identifiers

Expert(s)
Yoav Nir, Rich Salz, Nick Sullivan
Reference
[RFC5246][RFC8447]
Note
The role of the designated expert is described in [RFC8447].
The designated expert [RFC8126] ensures that the specification is
publicly available.  It is sufficient to have an Internet-Draft
(that is posted and never published as an RFC) or a document from
another standards body, industry consortium, university site, etc.
The expert may provide more in-depth reviews, but their approval
should not be taken as an endorsement of the identifier.
    
Note
As specified in [RFC8126], assignments made in the Private Use
space are not generally useful for broad interoperability.  It is
the responsibility of those making use of the Private Use range to
ensure that no conflicts occur (within the intended scope of use).
For widespread experiments, temporary reservations are available.
    
Note
The values in this registry are only applicable to (D)TLS
protocol versions prior to 1.3.

TLS Cipher Suites

Registration Procedure(s)
Specification Required
Expert(s)
Yoav Nir, Rich Salz, Nick Sullivan
Reference
[RFC8446][RFC8447]
Note
WARNING:  Cryptographic algorithms and parameters will be broken or
weakened over time.  Blindly implementing cipher suites listed here 
is not advised.  Implementers and users need to check that the 
cryptographic algorithms listed continue to provide the expected 
level of security.
    
Note
Although TLS 1.3 uses the same cipher suite space as previous
versions of TLS, TLS 1.3 cipher suites are defined differently,
only specifying the symmetric ciphers and hash function, and
cannot be used for TLS 1.2.  Similarly, TLS 1.2 and lower cipher
suite values cannot be used with TLS 1.3.
    
Note
CCM_8 cipher suites are not marked as "Recommended".  These
cipher suites have a significantly truncated authentication tag
that represents a security trade-off that may not be appropriate
for general environments.
    
Note
If an item is not marked as "Recommended", it does not
necessarily mean that it is flawed; rather, it indicates that
the item either has not been through the IETF consensus process,
has limited applicability, or is intended only for specific use
cases.
    
Note
The role of the designated expert is described in [RFC8447].
The designated expert [RFC8126] ensures that the specification is
publicly available.  It is sufficient to have an Internet-Draft
(that is posted and never published as an RFC) or a document from
another standards body, industry consortium, university site, etc.
The expert may provide more in-depth reviews, but their approval
should not be taken as an endorsement of the cipher suite.
    
Note
As specified in [RFC8126], assignments made in the Private Use
space are not generally useful for broad interoperability.  It is
the responsibility of those making use of the Private Use range to
ensure that no conflicts occur (within the intended scope of use).

TLS Supported Groups

Yoav Nir, Rich Salz, Nick Sullivan
Reference
[RFC8422][RFC7919][RFC8446][RFC8447]
Note
Renamed from "EC Named Curve Registry"
    
Note
If an item is not marked as "Recommended", it does not
necessarily mean that it is flawed; rather, it indicates that
the item either has not been through the IETF consensus process,
has limited applicability, or is intended only for specific use
cases.
    
Note
The role of the designated expert is described in [RFC8447].
The designated expert [RFC8126] ensures that the specification is
publicly available.  It is sufficient to have an Internet-Draft
(that is posted and never published as an RFC) or a document from
another standards body, industry consortium, university site, etc.
The expert may provide more in-depth reviews, but their approval
should not be taken as an endorsement of the supported group.
    
Note
WARNING: Cryptographic algorithms and parameters will be broken or
weakened over time.  Blindly implementing supported groups 
listed here is not advised.  Implementers and users need to check 
that the cryptographic algorithms listed continue to provide the 
expected level of security.

TLS Exporter Labels

Yoav Nir, Rich Salz, Nick Sullivan
Reference
[RFC5705][RFC8447]
Note
(1) These entries are reserved and MUST NOT be used for the 
purpose described in [RFC5705], in order to avoid confusion 
with similar, but distinct use in [RFC5246].
    
Note
[RFC5705] defines keying material exporters for TLS in terms
of the TLS PRF.  [RFC8446] replaced the PRF with HKDF,
thus requiring a new construction.  The exporter interface remains
the same; however, the value is computed differently.
    
Note
The role of the designated expert is described in [RFC8447].
The designated expert [RFC8126] ensures that the specification is
publicly available.  It is sufficient to have an Internet-Draft
(that is posted and never published as an RFC) or a document from
another standards body, industry consortium, university site, etc.
The expert may provide more in-depth reviews, but their approval
should not be taken as an endorsement of the exporter label.  The
expert also verifies that the label is a string consisting of
printable ASCII characters beginning with "EXPORTER".  IANA MUST
also verify that one label is not a prefix of any other label.
For example, labels "key" or "master secretary" are forbidden.
    
Note
If an item is not marked as "Recommended", it does not
necessarily mean that it is flawed; rather, it indicates that
the item either has not been through the IETF consensus process,
has limited applicability, or is intended only for specific use
cases.

WARNING: Cryptographic algorithms and parameters will be broken or

Note
As specified in [RFC8126], assignments made in the Private Use
space are not generally useful for broad interoperability.  It is
the responsibility of those making use of the Private Use range to
ensure that no conflicts occur (within the intended scope of use).
For widespread experiments, temporary reservations are available.

Reference
[RFC8446]
Note
If an item is not marked as "Recommended", it does not
necessarily mean that it is flawed; rather, it indicates that
the item either has not been through the IETF consensus process,
has limited applicability, or is intended only for specific use
cases.
    
Note
The role of the designated expert is described in [RFC8447].
The designated expert [RFC8126] ensures that the specification is
publicly available.  It is sufficient to have an Internet-Draft
(that is posted and never published as an RFC) or a document from
another standards body, industry consortium, university site, etc.
The expert may provide more in depth reviews, but their approval
should not be taken as an endorsement of the key exchange mode.
