View source for Comparison of TLS implementations

The [[Transport Layer Security]] (TLS) protocol provides the ability to secure communications across networks. This '''comparison of TLS implementations''' compares several of the most notable [[software library|libraries]]. There are several TLS implementations which are [[free software]] and [[open source]].

All comparison categories use the stable version of each implementation listed in the overview section. The comparison is limited to features that directly relate to the TLS protocol.

== Protocol support ==
Several versions of the TLS protocol exist. SSL 2.0 is a deprecated<ref name=ssl2diediedie>[//tools.ietf.org/html/rfc6176 RFC6176: Prohibiting Secure Sockets Layer (SSL) Version 2.0]</ref> protocol version with significant weaknesses.  SSL 3.0 (1996) and TLS 1.0 (1999) are successors with two weaknesses in CBC-padding that were explained in 2001 by Serge Vaudenay.<ref name="vaudenay-cbc">[http://infoscience.epfl.ch/record/52417/files/IC_TECH_REPORT_200150.pdf "CBC-Padding: Security Flaws in SSL, IPsec, WTLS,...", Serge Vaudenay, 2001]</ref>  TLS 1.1 (2006) fixed only one of the problems, by switching to random [[initialization vector]]s (IV) for CBC block ciphers, whereas the more problematic use of mac-pad-encrypt instead of the secure pad-mac-encrypt was addressed with RFC7366.<ref name=rfc7366>[//tools.ietf.org/html/rfc7366 RFC7366: Encrypt-then-MAC for Transport Layer Security (TLS) and Datagram Transport Layer Security]</ref>  A workaround for SSL 3.0 and TLS 1.0, roughly equivalent to random IVs from TLS 1.1, was widely adopted by many implementations in late 2011,<ref name="BEAST-countermeasure">[https://www.educatedguesswork.org/2011/11/rizzoduong_beast_countermeasur.html Rizzo/Duong BEAST Countermeasures]</ref> so from a security perspective, all existing version of TLS 1.0, 1.1 and 1.2 provide equivalent strength in the base protocol and are suitable for 128-bit security according to NIST SP800-57 up to at least 2030.  In 2014, the [[POODLE]] vulnerability of SSL 3.0 was discovered, which takes advantage the known vulnerabilities in CBC, and an insecure fallback negotiation used in browsers.<ref name="poodle">{{cite web | url=https://www.openssl.org/~bodo/ssl-poodle.pdf | title=This POODLE Bites: Exploiting The SSL 3.0 Fallback | date=September 2014 | accessdate=15 October 2014 |author1=Möller, Bodo |author2=Duong, Thai |author3=Kotowicz, Krzysztof }}</ref>

TLS 1.2 (2008) is the latest published version of the base protocol, introducing a means to identify the hash used for digital signatures.  While permitting the use of stronger hash functions for digital signatures in the future (rsa,sha256/sha384/sha512) over the SSL 3.0 conservative choice (rsa,sha1+md5), the TLS 1.2 protocol change inadvertently and substantially weakened the default digital signatures and provides (rsa,sha1) and even (rsa,md5).<ref name="TLSv1.2-changes">[//tools.ietf.org/html/rfc5246#section-1.2 TLSv1.2's Major Differences from TLSv1.1]</ref>

[[Datagram Transport Layer Security]] (DTLS or Datagram TLS) 1.0 is a modification of TLS 1.1 for a packet-oriented transport layer, where packet loss and packet reordering have to be tolerated.  The revision DTLS 1.2 based on TLS 1.2 was published in January 2012<ref name="RFC 6347">RFC 6347</ref>

Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0.  With the exception of the predictable IVs (for which an easy workaround exists) all currently known vulnerabilities affect all version of TLS 1.0/1.1/1.2 alike.<ref name=attacks>{{cite web | title = Bard attack | citeseerx = 10.1.1.61.5887 }}</ref>

== NSA Suite B Cryptography ==
Required components for [[NSA Suite B Cryptography]] (RFC 6460) are:
* [[Advanced Encryption Standard]] (AES) with key sizes of 128 and 256 bits. For traffic flow, AES should be used with either the Counter Mode (CTR) for low bandwidth traffic or the [[Galois/Counter Mode]] (GCM) mode of operation for high bandwidth traffic (see [[Block cipher modes of operation]]) — [[symmetric encryption]]
* [[Elliptic Curve Digital Signature Algorithm]] (ECDSA) — [[digital signature]]s
* [[Elliptic Curve Diffie–Hellman]]  (ECDH) — [[key agreement]]
* [[SHA-2|Secure Hash Algorithm 2]] (SHA-256 and SHA-384) — [[message digest]]

Per CNSSP-15, the 256-bit elliptic curve (specified in FIPS 186-2), SHA-256, and AES with 128-bit keys are sufficient for protecting classified information up to the [[Security clearance#Secret|Secret]] level, while the 384-bit elliptic curve (specified in FIPS 186-2), SHA-384, and AES with 256-bit keys are necessary for the protection of [[Security clearance#Top Secret|Top Secret]] information.

== Compression ==
Note the [[CRIME (security exploit)|CRIME security exploit]] takes advantage of TLS compression, so conservative implementations do not enable compression at the TLS level. [[HTTP compression]] is unrelated and unaffected by this exploit, but is exploited by the related [[BREACH (security exploit)|BREACH attack]].

== Extensions ==
In this section the extensions each implementation supports are listed. Note that the Secure Renegotiation extension is critical for HTTPS client security {{citation needed|date=August 2014}}. TLS clients not implementing it are vulnerable to attacks, irrespective of whether the client implements TLS renegotiation.
