21### Major changes between OpenSSL 3.0.2 and OpenSSL 3.0.3 [3 May 2022]
22
23 * Fixed a bug in the c_rehash script which was not properly sanitising shell
24 metacharacters to prevent command injection ([CVE-2022-1292])
25 * Fixed a bug in the function `OCSP_basic_verify` that verifies the signer
26 certificate on an OCSP response ([CVE-2022-1343])
27 * Fixed a bug where the RC4-MD5 ciphersuite incorrectly used the
28 AAD data as the MAC key ([CVE-2022-1434])
29 * Fix a bug in the OPENSSL_LH_flush() function that breaks reuse of the memory
30 occuppied by the removed hash table entries ([CVE-2022-1473])
31
32### Major changes between OpenSSL 3.0.1 and OpenSSL 3.0.2 [15 Mar 2022]
33
34 * Fixed a bug in the BN_mod_sqrt() function that can cause it to loop forever
35 for non-prime moduli ([CVE-2022-0778])
36
37### Major changes between OpenSSL 3.0.0 and OpenSSL 3.0.1 [14 Dec 2021]
38
39 * Fixed invalid handling of X509_verify_cert() internal errors in libssl
40 ([CVE-2021-4044])
41 * Allow fetching an operation from the provider that owns an unexportable key

44### Major changes between OpenSSL 1.1.1 and OpenSSL 3.0.0 [7 sep 2021]
45
46 * Enhanced 'openssl list' with many new options.
47 * Added migration guide to man7.
48 * Implemented support for fully "pluggable" TLSv1.3 groups.
49 * Added suport for Kernel TLS (KTLS).
50 * Changed the license to the Apache License v2.0.
51 * Moved all variations of the EVP ciphers CAST5, BF, IDEA, SEED, RC2,
52 RC4, RC5, and DES to the legacy provider.
53 * Moved the EVP digests MD2, MD4, MDC2, WHIRLPOOL and RIPEMD-160 to the legacy
54 provider.
55 * Added convenience functions for generating asymmetric key pairs.
56 * Deprecated the `OCSP_REQ_CTX` type and functions.
57 * Deprecated the `EC_KEY` and `EC_KEY_METHOD` types and functions.
58 * Deprecated the `RSA` and `RSA_METHOD` types and functions.
59 * Deprecated the `DSA` and `DSA_METHOD` types and functions.
60 * Deprecated the `DH` and `DH_METHOD` types and functions.

72 certificates signed using SHA1 are by default no longer trusted to
73 authenticate servers or clients.
74 * enable-crypto-mdebug and enable-crypto-mdebug-backtrace were mostly
75 disabled; the project uses address sanitize/leak-detect instead.

107 * All of the low-level MD2, MD4, MD5, MDC2, RIPEMD160, SHA1, SHA224,
108 SHA256, SHA384, SHA512 and Whirlpool digest functions have been
109 deprecated.
110 * All of the low-level AES, Blowfish, Camellia, CAST, DES, IDEA, RC2,
111 RC4, RC5 and SEED cipher functions have been deprecated.
112 * All of the low-level DH, DSA, ECDH, ECDSA and RSA public key functions
113 have been deprecated.
114 * SSL 3, TLS 1.0, TLS 1.1, and DTLS 1.0 only work at security level 0.
