Botan 1.7.22 (Development branch)
Botan is a C++ library of cryptographic algorithms, including AES, DES, SHA-1, RSA, DSA, Diffie-Hellman, and many others. It also supports X.509 certificates and CRLs, and PKCS #10 certificate requests, and has a high level filter/pipe message processing system. The library is easily portable to most systems and compilers, and includes a substantial tutorial and API reference.License: BSD License (revised)Changes:
This release adds much finer grained control ofalgorithm provider specifications, allowingapplications to more easily choose amongimplementations. Nested constructions like HMACand CMAC now properly acquire the preferredimplementations rather than always using thebaseline C++ implementations. The AESimplementation has been optimized somewhat, and isabout 10% faster on x86-64 processors. Severalmemory leaks introduced in PBE_PKCS5v20 in theprevious release have also been fixed.Image

x509(3) 							      OpenSSL								   x509(3)

NAME

       x509 - X.509 certificate handling

SYNOPSIS

	#include <openssl/x509.h>

DESCRIPTION

       A X.509 certificate is a structured grouping of information about an individual, a device, or anything one can imagine.	A X.509 CRL
       (certificate revocation list) is a tool to help determine if a certificate is still valid.  The exact definition of those can be found in
       the X.509 document from ITU-T, or in RFC3280 from PKIX.	In OpenSSL, the type X509 is used to express such a certificate, and the type
       X509_CRL is used to express a CRL.

       A related structure is a certificate request, defined in PKCS#10 from RSA Security, Inc, also reflected in RFC2896.  In OpenSSL, the type
       X509_REQ is used to express such a certificate request.

       To handle some complex parts of a certificate, there are the types X509_NAME (to express a certificate name), X509_ATTRIBUTE (to express a
       certificate attributes), X509_EXTENSION (to express a certificate extension) and a few more.

       Finally, there's the supertype X509_INFO, which can contain a CRL, a certificate and a corresponding private key.

       X509_..., d2i_X509_... and i2d_X509_... handle X.509 certificates, with some exceptions, shown below.

       X509_CRL_..., d2i_X509_CRL_... and i2d_X509_CRL_...  handle X.509 CRLs.

       X509_REQ_..., d2i_X509_REQ_... and i2d_X509_REQ_...  handle PKCS#10 certificate requests.

       X509_NAME_... handle certificate names.

       X509_ATTRIBUTE_... handle certificate attributes.

       X509_EXTENSION_... handle certificate extensions.
