-GOST ENGINE
+OPENSSL GOST ENGINE
 
-This engine provides implementation of Russian cryptography standard.
-This is also an example of adding new cryptoalgorithms into OpenSSL
-without changing its core. If OpenSSL is compiled with dynamic engine

-OpenSSL and applications which use it.
+An implementation of Russian cryptography standards for OpenSSL.
+
+Since v.1.0.0 OpenSSL provides facilities for creating external
+dynamically loaded cryptographic engines (OpenSSL should be built
+with dynamic engine support to be able to use it).
+
+This engine provides an implementation of various Russian cryptographic
+algorithms, known generally as GOST cryptographic algorithms (see detailed
+list below). These algorithms, can be used both via OpenSSL command line
+tools and via high-level libopenssl calls.
+
+OpenSSL GOST Engine also includes gostsum и gost12sum command line tools,
+for generating and checking GOST R34.11-94 and GOST R34.11-2012 hash sums.
+They have the same purposes and behavior as well known sha1sum and md5sum
+utilities.
