+=head1 NAME
+
+crypto - OpenSSL cryptographic library
+
+=head1 SYNOPSIS
+
+See the individual manual pages for details.
+
+=head1 DESCRIPTION
+
+The OpenSSL B<crypto> library implements a wide range of cryptographic
+algorithms used in various Internet standards. The services provided
+by this library are used by the OpenSSL implementations of SSL, TLS
+and S/MIME, and they have also been used to implement SSH, OpenPGP, and
+other cryptographic standards.
+
+B<libcrypto> consists of a number of sub-libraries that implement the
+individual algorithms.
+
+The functionality includes symmetric encryption, public key
+cryptography and key agreement, certificate handling, cryptographic
+hash functions, cryptographic pseudo-random number generator, and
+various utilities.
+
+=head1 NOTES
+
+Some of the newer functions follow a naming convention using the numbers
+B<0> and B<1>. For example the functions:
+
+ int X509_CRL_add0_revoked(X509_CRL *crl, X509_REVOKED *rev);
+ int X509_add1_trust_object(X509 *x, const ASN1_OBJECT *obj);
+
+The B<0> version uses the supplied structure pointer directly
+in the parent and it will be freed up when the parent is freed.
+In the above example B<crl> would be freed but B<rev> would not.
+
+The B<1> function uses a copy of the supplied structure pointer
+(or in some cases increases its link count) in the parent and
+so both (B<x> and B<obj> above) should be freed up.
+
