What's sgcIndy Package?

The origin of the sgcIndy Package started when several sgcWebSockets users were concerned about the lack of support of the latest openSSL libraries by the Indy Library (which officially only supports the deprecated 1.0.2 version), initially only the sgcWebSockets library implemented the new openSSL versions, but lots of users are still using the Indy components in production (FTP, SMTP servers...) and I got several requests to implement these features to override the security problems using the deprecated 1.0.2 openSSL libraries. sgcIndy Package tries to fix these problems providing access to the latest OpenSSL 1.1.1 & 3.0.0 libraries and adding support for other features like ALPN and more.

OpenSSL 1.1.1 & 3.0.0 Support

Supports latest OpenSSL libraries 1.1.1 & 3.0.0. Widest compatibility via support for modern TLS 1.3 and secure your messages using latest OpenSSL version.

Just set global variable called OPENSSL_API_VERSION located in IdSSLOpenSSLHeaders to opSSL_1_1.

OPENSSL_API_VERSION := opSSL_1_1;

Just set global variable called OPENSSL_API_VERSION located in IdSSLOpenSSLHeaders to opSSL_3_0.

OPENSSL_API_VERSION := opSSL_3_0;

ALPN Protocol

Application-Layer Protocol Negotiation. The ever-growing in popularity HTTP/2 protocol, makes use of ALPN to further decrease website load times and encrypt connections faster.

Cipher List

Allows to configure which Ciphers will be used (separated by ":"). Example: CALG_AES_256:CALG_AES_128

Legacy Providers

From OpenSSL 3.0 some functions have been deprecated and are only available using a legacy library, you can optional enable the legacy library to provide support for old legacy code.

XOAuth2 Authentication

This document defines the SASL XOAUTH2 mechanism for use with the IMAP AUTHENTICATE, POP AUTH, and SMTP AUTH commands. This mechanism allows for example the use of OAuth 2.0 Access Tokens to authenticate to a user's Gmail account.
