Update to 3.5.0:
* Changes:
- Default encryption cipher for the req, cms, and smime applications
changed from des-ede3-cbc to aes-256-cbc.
- The default TLS supported groups list has been changed to include
and prefer hybrid PQC KEM groups. Some practically unused groups
were removed from the default list.
- The default TLS keyshares have been changed to offer X25519MLKEM768
and and X25519.
- All BIO_meth_get_*() functions were deprecated.
* New features:
- Support for server side QUIC (RFC 9000)
- Support for 3rd party QUIC stacks including 0-RTT support
- Support for PQC algorithms (ML-KEM, ML-DSA and SLH-DSA)
- A new configuration option no-tls-deprecated-ec to disable support
for TLS groups deprecated in RFC8422
- A new configuration option enable-fips-jitter to make the FIPS
provider to use the JITTER seed source
- Support for central key generation in CMP
- Support added for opaque symmetric key objects (EVP_SKEY)
- Support for multiple TLS keyshares and improved TLS key establishment
group configurability
- API support for pipelining in provided cipher algorithms
Changes between 3.3.0 and 3.4.0:
* Changes:
- Deprecation of TS_VERIFY_CTX_set_* functions and addition of
replacement TS_VERIFY_CTX_set0_* functions with improved semantics
- The X25519 and X448 key exchange implementation in the FIPS provider
is unapproved and has fips=no property.
- SHAKE-128 and SHAKE-256 implementations have no default digest length
anymore. That means these algorithms cannot be used with
EVP_DigestFinal/_ex() unless the xoflen param is set before.
- Setting config_diagnostics=1 in the config file will cause errors to
be returned from SSL_CTX_new() and SSL_CTX_new_ex() if there is an
error in the ssl module configuration.
- An empty renegotiate extension will be used in TLS client hellos
instead of the empty renegotiation SCSV, for all connections with a
minimum TLS version > 1.0.
- Deprecation of SSL_SESSION_get_time(), SSL_SESSION_set_time() and
SSL_CTX_flush_sessions() functions in favor of their respective _ex
functions which are Y2038-safe on platforms with Y2038-safe time_t
* New features:
- Support for directly fetched composite signature algorithms such as
RSA-SHA2-256 including new API functions
- FIPS indicators support in the FIPS provider and various updates of
the FIPS provider required for future FIPS 140-3 validations
- Implementation of RFC 9579 (PBMAC1) in PKCS#12
- An optional additional random seed source RNG JITTER using a statically
linked jitterentropy library
- New options -not_before and -not_after for explicit setting start and
end dates of certificates created with the req and x509 apps
- Support for integrity-only cipher suites TLS_SHA256_SHA256 and
TLS_SHA384_SHA384 in TLS 1.3, as defined in RFC 9150
- Support for retrieving certificate request templates and CRLs in CMP
- Support for additional X.509v3 extensions related to Attribute Certificates
- Initial Attribute Certificate (RFC 5755) support
- Possibility to customize ECC groups initialization to use precomputed
values to save CPU time and use of this feature by the P-256 implementation
Changes between 3.2.0 and 3.3.0:
* Changes:
- Optimized AES-CTR for ARM Neoverse V1 and V2
- Various optimizations for cryptographic routines using RISC-V vector
crypto extensions
- Added assembly implementation for md5 on loongarch64
- Accept longer context for TLS 1.2 exporters
- The activate and soft_load configuration settings for providers in
openssl.cnf have been updated to require a value of [1|yes|true|on]
(in lower or UPPER case) to enable the setting. Conversely a value of
[0|no|false|off] will disable the setting.
- In openssl speed, changed the default hash function used with hmac from
md5 to sha256.
- The -verify option to the openssl crl and openssl req will make the
program exit with 1 on failure.
- The d2i_ASN1_GENERALIZEDTIME(), d2i_ASN1_UTCTIME(), ASN1_TIME_check(),
and related functions have been augmented to check for a minimum length
of the input string, in accordance with ITU-T X.690 section 11.7 and 11.8.
- OPENSSL_sk_push() and sk__push() functions now return 0 instead of -1
if called with a NULL stack argument.
- New limit on HTTP response headers is introduced to HTTP client.
The default limit is set to 256 header lines.
* Bug fixes and mitigations:
- The BIO_get_new_index() function can only be called 127 times before
it reaches its upper bound of BIO_TYPE_MASK and will now return -1
once its exhausted.
* new features:
- Support for qlog for tracing QUIC connections has been added
- Added APIs to allow configuring the negotiated idle timeout for QUIC
connections, and to allow determining the number of additional streams
that can currently be created for a QUIC connection.
- Added APIs to allow disabling implicit QUIC event processing for QUIC
SSL objects
- Added APIs to allow querying the size and utilisation of a QUIC
stream's write buffer
- New API SSL_write_ex2, which can be used to send an end-of-stream (FIN)
condition in an optimised way when using QUIC.
- Limited support for polling of QUIC connection and stream objects in a
non-blocking manner.
- Added a new EVP_DigestSqueeze() API. This allows SHAKE to squeeze multiple
times with different output sizes.
- The BLAKE2s hash algorithm matches BLAKE2b's support for configurable
output length.
- The EVP_PKEY_fromdata function has been augmented to allow for the
derivation of CRT (Chinese Remainder Theorem) parameters when requested
- Added API functions SSL_SESSION_get_time_ex(), SSL_SESSION_set_time_ex()
using time_t which is Y2038 safe on 32 bit systems when 64 bit time
is enabled.
- Unknown entries in TLS SignatureAlgorithms, ClientSignatureAlgorithms
config
options and the respective calls to SSL[_CTX]_set1_sigalgs() and
SSL[_CTX]_set1_client_sigalgs() that start with ? character are ignored
and the configuration will still be used.
- Added -set_issuer and -set_subject options to openssl x509 to override
the Issuer and Subject when creating a certificate. The -subj option
now is an alias for -set_subject.
- Added several new features of CMPv3 defined in RFC 9480 and RFC 9483
- New option SSL_OP_PREFER_NO_DHE_KEX, which allows configuring a TLS1.3
server to prefer session resumption using PSK-only key exchange over
PSK with DHE, if both are available.
- New atexit configuration switch, which controls whether the OPENSSL_cleanup
is registered when libcrypto is unloaded.
- Added X509_STORE_get1_objects to avoid issues with the existing
X509_STORE_get0_objects API in multi-threaded applications.
- Support for using certificate profiles and extened delayed delivery in CMP
- FIPS: Mark SHA-1 as non-approved in the SLI. [jsc#PED-12224]
- Introduce --without lto. When %{optflags} contains -flto=*, tests cases are
also built using -flto=* which significantly increases build times, this
option disables lto which improve iteration times when developing.
Update to 3.2.4:
- Remove the engines' directories and symlinks that were added to
allow parallel installations with openssl-1_1.
- Add ktls capability [bsc#1216950]
