Kathleen and Andrew Booth's team at Birkbeck were considered the smallest of the early British computer groups.

'''CyaSSL''' (or yet another SSL) is a small, portable, embedded SSL programming library targeted for use by embedded systems developers. It is an [[open source]], implementation of [[Secure Sockets Layer|SSL]] (SSL 3, TLS 1.0, 1.1, and TLS 1.2) built in the [[C (programming language)|C language]]. It includes SSL client libraries and an SSL server implementation as well as support for multiple API's, including those defined by [[Secure Sockets Layer|SSL]] and [[Transport Layer Security|TLS]]. CyaSSL also includes an [[OpenSSL]] compatibility interface with the most commonly used OpenSSL functions.<ref name="compatibility">[http://yassl.com/yaSSL/Products.html yaSSL: Products, OpenSSL Compatibility Layer]</ref>

==Platforms==
CyaSSL is currently available for [[Windows API|Win32/64]], [[Linux]], [[Solaris (operating system)|Solaris]], [[FreeBSD]], [[NetBSD]], [[OpenBSD]], [[Mac OS X]], [[OpenWRT]], [[iPhone]], [[Wii|Nintendo Wii]] and [[Nintendo GameCube|Gamecube]] through DevKitPro support, [[QNX]], [[VxWorks]], [[MontaVista]], [[ThreadX]], [[TRON Project|Tron]] variants, [[OpenCL]] and [[CUDA]].

==History==
The first major user of CyaSSL/yaSSL was [[MySQL]],<ref>[http://dev.mysql.com/doc/refman/5.1/en/secure-using-ssl.html MySQL, Using SSL Connections]</ref> the world's most popular open source database. Through bundling with MySQL, yaSSL has achieved extremely high distribution volumes in the millions.

Today CyaSSL is used in both open source and commercial projects.<ref>[http://yassl.com/yaSSL/Community.html Projects using yaSSL]</ref> CyaSSL is included in many types of network devices such as smart devices on automobiles, IP phones, mobile phones, routers, printers, and credit card scanners.

==Protocols==
{{main|Transport Layer Security}}
CyaSSL for embedded SSL implements the SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2 protocols.<ref name="protocols">[http://yassl.com/yaSSL/Docs_References.html yaSSL: Algorithm and Protocol Reference]</ref>

==Algorithms==
CyaSSL uses the following cryptography libraries:

===TaoCrypt===
By default, CyaSSL uses the cryptographic services provided by TaoCrypt<ref>[http://yassl.com/arch.html#taocrypt TaoCrypt]</ref> which is based in part on Crypto++ (see below). TaoCrypt strives to be more portable while only providing the functionality necessary for SSL type needs. TaoCrypt Provides [[RSA]], [[DES]], [[3DES]], [[ARC4]], [[MD2]], [[MD5]], [[SHA-1]], [[RIPEMD-160]], [[DSS]], [[Diffie-Hellman]], Random Number Generation, Large Integer support, and base 16/64 encoding/decoding. An experimental cipher called [[Rabbit (cipher)|Rabbit]], a public domain stream cipher from the EU's eSTREAM project, is also included. Rabbit is potentially useful to those encrypting streaming media in high performance, high demand environments. Support for a FIPS validated crypto module is provided by CryptoPP, below.

===Crypto++===
[[Crypto++]]<ref>[http://www.cryptopp.com/ Crypto++]</ref> can also be used to handle cryptography and crypto related details. [[RSA]], [[DES]], [[3DES]], [[ARC4]], [[MD5]], [[SHA-1]], and [[DSS]] are currently used by CyaSSL,<ref name="protocols"/> as well as Crypto++'s cryptographically secure random number generator, large Integer support, and base64 encoding/decoding. Crypto++ includes a precompiled FIPS 140-2 level one crypto module (for Windows) that may be used as well.

===NTRU===
CyaSSL+ includes [[NTRUEncrypt|NTRU]] <ref name="securityinnovation">[http://securityinnovation.com/cryptolab/ NTRU CryptoLabs]</ref> public key encryption. The addition of NTRU in CyaSSL+ was a result of the partnership between yaSSL and Security Innovations <ref name="securityinnovation"></ref>. NTRU works well in mobile and embedded environments due to the reduced bit size needed to provide the same security as other public key systems. In addition, it's not vulnerable to quantum attacks. Several cipher suites utilizing NTRU are available with CyaSSL+ including AES-256, RC4, and HC-128.

==Product history==

'''CyaSSL''' (or yet another SSL) is a small, portable, embedded SSL programming library targeted for use by embedded systems developers. It is an [[open source]], implementation of [[Secure Sockets Layer|SSL]] (SSL 3, TLS 1.0, 1.1, and TLS 1.2) built in the [[C (programming language)|C language]]. It includes SSL client libraries and an SSL server implementation as well as support for multiple API's, including those defined by [[Secure Sockets Layer|SSL]] and [[Transport Layer Security|TLS]]. CyaSSL also includes an [[OpenSSL]] compatibility interface with the most commonly used OpenSSL functions.<ref name="compatibility">[http://yassl.com/yaSSL/Products.html yaSSL: Products, OpenSSL Compatibility Layer]</ref>

==Platforms==
CyaSSL is currently available for [[Windows API|Win32/64]], [[Linux]], [[Solaris (operating system)|Solaris]], [[FreeBSD]], [[NetBSD]], [[OpenBSD]], [[Mac OS X]], [[OpenWRT]], [[iPhone]], [[Wii|Nintendo Wii]] and [[Nintendo GameCube|Gamecube]] through DevKitPro support, [[QNX]], [[VxWorks]], [[MontaVista]], [[ThreadX]], [[TRON Project|Tron]] variants, [[OpenCL]] and [[CUDA]].

==History==
The first major user of CyaSSL/yaSSL was [[MySQL]],<ref>[http://dev.mysql.com/doc/refman/5.1/en/secure-using-ssl.html MySQL, Using SSL Connections]</ref> the world's most popular open source database. Through bundling with MySQL, yaSSL has achieved extremely high distribution volumes in the millions.

Today CyaSSL is used in both open source and commercial projects.<ref>[http://yassl.com/yaSSL/Community.html Projects using yaSSL]</ref> CyaSSL is included in many types of network devices such as smart devices on automobiles, IP phones, mobile phones, routers, printers, and credit card scanners.

==Protocols==
{{main|Transport Layer Security}}
CyaSSL for embedded SSL implements the SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2 protocols.<ref name="protocols">[http://yassl.com/yaSSL/Docs_References.html yaSSL: Algorithm and Protocol Reference]</ref>

==Algorithms==
CyaSSL uses the following cryptography libraries:

===TaoCrypt===
By default, CyaSSL uses the cryptographic services provided by TaoCrypt<ref>[http://yassl.com/arch.html#taocrypt TaoCrypt]</ref> which is based in part on CryptoPP (see below). TaoCrypt aims to be more portable while only providing the functionality necessary for SSL type needs. TaoCrypt Provides [[RSA]], [[DES]], [[3DES]], [[ARC4]], [[MD2]], [[MD5]], [[SHA-1]], [[RIPEMD-160]], [[DSS]], [[Diffie-Hellman]], Random Number Generation, Large Integer support, and base 16/64 encoding/decoding. An experimental cipher called [[Rabbit (cipher)|Rabbit]], a public domain stream cipher from the EU's eSTREAM project, is also included. Rabbit is potentially useful to those encrypting streaming media in high performance, high demand environments. Support for a FIPS validated crypto module is provided by CryptoPP, below.

===Crypto++===
[[Crypto++|CryptoPP]]<ref>[http://www.cryptopp.com/ CryptoPP]</ref> can also be used to handle cryptography and crypto related details. [[RSA]], [[DES]], [[3DES]], [[ARC4]], [[MD5]], [[SHA-1]], and [[DSS]] are currently used by CyaSSL,<ref name="protocols"/> as well as CryptoPP's cryptographically secure random number generator, large Integer support, and base64 encoding/decoding. CryptoPP includes a FIPS 140-2 level one crypto module that may be used as well.
