-It is aimed to provide Python interface to OpenSSL libcrypto functions.
-All the objects in this library are just wrappers around some OpenSSL
-data structures and groups of functions.
+Rationale
+---------
+
+Why have yet another crypto extension for Python? There is pyopenssl,
+m2crypto, hashlib in the standard library and many more.
+
+But most of these extension implement interfaces to particular set of
+cryptoalgorthms. This extension takes an another approach — it uses
+algorithm-agnostic EVP layer whenever possible, and so support any
+algorithms which are supported by underlying library, even this
+algorithms are implemented in the loadable modules (engines). Algorithms
+which you've just added to library, should be supported too.
+
+Also, this extension takes some care of correctly converting textual
+information from ASN.1 structures into unicode.

 and even fewer, that OpenSSL supports them.
