Note
If the "Specification Required" [
RFC8126
] procedure applies,
registration requests can be sent to iana@iana.org or submitted via
IANA's [
application form
], per [
RFC9847
]. IANA
will forward the submission to the expert mailing list described in
RFC 8447, Section 17
] and track its progress. See the registration
procedure table below for more information.
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.
Note
Any TLS entry added after the IESG approves publication of [
RFC-ietf-tls-tls12-frozen-08
is intended for TLS 1.3 or later, and makes no similar requirement
on DTLS. Such entries should have an informal indication like "For
TLS 1.3 or later" in that entry, such as the "Comment" column.
Note
If the "Recommended" column is set to "N", 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. If the
"Recommended" column is set to "D," the item is discouraged and
SHOULD NOT or MUST NOT be used, depending upon the situation;
consult the item's references for clarity.

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 the "Recommended" column is set to "N", 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. If the
"Recommended" column is set to "D," the item is discouraged and
SHOULD NOT or MUST NOT be used, depending upon the situation;
consult the item's references for clarity.
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).
For widespread experiments, temporary reservations are available.
Note
Any TLS cipher suite that is specified for use with DTLS MUST
define limits on the use of the associated AEAD function that
preserves margins for both confidentiality and integrity,
as specified in Section 4.5.3 of [
RFC9147
].
Note
When this registry is modified, the YANG module
"iana-tls-cipher-suite-algs" [
iana-tls-cipher-suite-algs
] must be
updated as defined in [
RFC9645
].
Note
Any TLS entry added after the IESG approves publication of [
RFC-ietf-tls-tls12-frozen-08
is intended for TLS 1.3 or later, and makes no similar requirement
on DTLS. Such entries should have an informal indication like "For
TLS 1.3 or later" in that entry, such as the "Comment" column.

Note
If the "Specification Required" [
RFC8126
] procedure applies,
registration requests can be sent to iana@iana.org or submitted via
IANA's [
application form
], per [
RFC9847
]. IANA
will forward the submission to the expert mailing list described in
RFC 8447, Section 17
] and track its progress. See the registration
procedure table below for more information.
Note
Renamed from "EC Named Curve Registry"
Note
If the "Recommended" column is set to "N", 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. If the
"Recommended" column is set to "D," the item is discouraged and
SHOULD NOT or MUST NOT be used, depending upon the situation;
consult the item's references for clarity.
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.
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.
Note
Any TLS entry added after the IESG approves publication of [

Note
If the "Expert Review" [
RFC8126
] procedure applies, registration
requests can be sent to iana@iana.org or submitted via IANA's
application form
], per [
RFC9847
]. IANA will
forward the submission to the expert mailing list described in
RFC 8447, Section 17
] and track its progress. See the registration
procedure table below for more information.
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. [
RFC-ietf-tls-rfc8446bis-13
] 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
RFC 8447, Section 17
]. Even though this registry does not require a
specification, the designated expert [
RFC8126
] will strongly
encourage registrants to provide a link to a publicly available
specification. An Internet-Draft (that is posted and never published
as an RFC) or a document from another standards body, industry
consortium, university site, etc. are suitable for these purposes.
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 the "Recommended" column is set to "N", 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. If the
"Recommended" column is set to "D," the item is discouraged and
SHOULD NOT or MUST NOT be used, depending upon the situation;
consult the item's references for clarity.

WARNING
Cryptographic algorithms and parameters will be broken or

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
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
If the "Specification Required" [
RFC8126
] procedure applies,
registration requests can be sent to iana@iana.org or submitted via
IANA's [
application form
], per [
RFC9847
]. IANA
will forward the submission to the expert mailing list described in
RFC 8447, Section 17
] and track its progress. See the registration
procedure table below for more information.
Note
If the "Recommended" column is set to "N", 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. If the
"Recommended" column is set to "D," the item is discouraged and
SHOULD NOT or MUST NOT be used, depending upon the situation;
consult the item's references for clarity.
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.
Note
Any TLS entry added after the IESG approves publication of [
RFC-ietf-tls-tls12-frozen-08
is intended for TLS 1.3 or later, and makes no similar requirement
on DTLS. Such entries should have an informal indication like "For
TLS 1.3 or later" in that entry, such as the "Comment" column.

registrations (Section 4.13 of [

Footnote
[1]
These values were allocated from the Reserved state due to a
misunderstanding of the difference between Reserved and Unallocated
that went undetected for a long time. Additional allocations from
the Reserved state are not expected, and the TLS SignatureScheme
registry is suitable for use for new allocations instead of this
registry.
