- This version of OpenSSL is an initial port of the FIPS 140-2 code to OpenSSL
|
|
|
5820f5 |
- 0.9.8. See the file README.FIPS for brief usage details.
|
|
|
5820f5 |
+ This version of OpenSSL is based on upstream openssl-fips-1.2.0 code
|
|
|
5820f5 |
+ which is also undergoing FIPS validation.
|
|
|
5820f5 |
+
|
|
|
5820f5 |
+ However this version contains a few differences from the upstream code
|
|
|
5820f5 |
+ some of which are:
|
|
|
5820f5 |
+ * The module respects the kernel FIPS flag /proc/sys/crypto/fips and
|
|
|
5820f5 |
+ tries to initialize the FIPS mode if it is set to 1 aborting if the
|
|
|
5820f5 |
+ FIPS mode could not be initialized. It is also possible to force the
|
|
|
5820f5 |
+ OpenSSL library to FIPS mode especially for debugging purposes by
|
|
|
5820f5 |
+ setting the environment variable OPENSSL_FORCE_FIPS_MODE.
|
|
|
5820f5 |
+ * If the environment variable OPENSSL_DEFAULT_ZLIB is set the module
|
|
|
5820f5 |
+ will automatically load the built in compression method ZLIB
|
|
|
5820f5 |
+ when initialized. Applications can still explicitely ask for ZLIB
|
|
|
5820f5 |
+ compression method with API calls. Otherwise the compression is not
|
|
|
5820f5 |
+ loaded and used due to protocol vulnerability as described in the
|
|
|
5820f5 |
+ CRIME attack.
