{: @abstract(Utilities for handling ASN.1 BER encoding)
By this unit you can parse ASN.1 BER encoded data to elements or build back any
elements to ASN.1 BER encoded buffer. You can dump ASN.1 BER encoded data to
human readable form for easy debugging, too.
Supported element types are: ASN1_BOOL, ASN1_INT, ASN1_OCTSTR, ASN1_NULL,
ASN1_OBJID, ASN1_ENUM, ASN1_SEQ, ASN1_SETOF, ASN1_IPADDR, ASN1_COUNTER,
ASN1_GAUGE, ASN1_TIMETICKS, ASN1_OPAQUE
For sample of using, look to @link(TSnmpSend) or @link(TLdapSend)class.

{:@abstract(SSL/SSH plugin for CryptLib)
This plugin requires cl32.dll at least version 3.2.0! It can be used on Win32
and Linux. This library is staticly linked - when you compile your application
with this plugin, you MUST distribute it with Cryptib library, otherwise you
cannot run your application!
It can work with keys and certificates stored as PKCS#15 only! It must be stored
as disk file only, you cannot load them from memory! Each file can hold multiple
keys and certificates. You must identify it by 'label' stored in
@link(TSSLCryptLib.PrivateKeyLabel).
If you need to use secure connection and authorize self by certificate
(each SSL/TLS server or client with client authorization), then use
@link(TCustomSSL.PrivateKeyFile), @link(TSSLCryptLib.PrivateKeyLabel) and
@link(TCustomSSL.KeyPassword) properties.
If you need to use server what verifying client certificates, then use
@link(TCustomSSL.CertCAFile) as PKCS#15 file with public keyas of allowed clients. Clients
with non-matching certificates will be rejected by cryptLib.
This plugin is capable to create Ad-Hoc certificates. When you start SSL/TLS
server without explicitly assigned key and certificate, then this plugin create
Ad-Hoc key and certificate for each incomming connection by self. It slowdown
accepting of new connections!
You can use this plugin for SSHv2 connections too! You must explicitly set
@link(TCustomSSL.SSLType) to value LT_SSHv2 and set @link(TCustomSSL.username)
and @link(TCustomSSL.password). You can use special SSH channels too, see
@link(TCustomSSL).

//requires OpenSSL libraries!
{:@abstract(SSL plugin for OpenSSL)
You need OpenSSL libraries version 0.9.7. It can work with 0.9.6 too, but
application mysteriously crashing when you are using freePascal on Linux.
Use Kylix on Linux is OK! If you have version 0.9.7 on Linux, then I not see
any problems with FreePascal.
OpenSSL libraries are loaded dynamicly - you not need OpenSSl librares even you
compile your application with this unit. SSL just not working when you not have
OpenSSL libraries.
This plugin have limited support for .NET too! Because is not possible to use
callbacks with CDECL calling convention under .NET, is not supported
key/certificate passwords and multithread locking. :-(
For handling keys and certificates you can use this properties:
@link(TCustomSSL.CertificateFile) for PEM or ASN1 DER (cer) format. @br
@link(TCustomSSL.Certificate) for ASN1 DER format only. @br
@link(TCustomSSL.PrivateKeyFile) for PEM or ASN1 DER (key) format. @br
@link(TCustomSSL.PrivateKey) for ASN1 DER format only. @br
@link(TCustomSSL.CertCAFile) for PEM CA certificate bundle. @br
@link(TCustomSSL.PFXFile) for PFX format. @br
@link(TCustomSSL.PFX) for PFX format from binary string. @br
This plugin is capable to create Ad-Hoc certificates. When you start SSL/TLS
server without explicitly assigned key and certificate, then this plugin create
Ad-Hoc key and certificate for each incomming connection by self. It slowdown
accepting of new connections!

{:@abstract(SSL plugin for StreamSecII or OpenStreamSecII)
StreamSecII is native pascal library, you not need any external libraries!
You can tune lot of StreamSecII properties by using your GlobalServer. If you not
using your GlobalServer, then this plugin create own TSimpleTLSInternalServer
instance for each TCP connection. Formore information about GlobalServer usage
refer StreamSecII documentation.
If you are not using key and certificate by GlobalServer, then you can use
properties of this plugin instead, but this have limited features and
@link(TCustomSSL.KeyPassword) not working properly yet!
For handling keys and certificates you can use this properties:
@link(TCustomSSL.CertCAFile), @link(TCustomSSL.CertCA),
@link(TCustomSSL.TrustCertificateFile), @link(TCustomSSL.TrustCertificate),
@link(TCustomSSL.PrivateKeyFile), @link(TCustomSSL.PrivateKey),
@link(TCustomSSL.CertificateFile), @link(TCustomSSL.Certificate),
@link(TCustomSSL.PFXFile). For usage of this properties and for possible formats
of keys and certificates refer to StreamSecII documentation.
