BP-Tools: SSL certificates with BP-CCALC


EFTlab

The SSL (Secure Sockets Layer) and TLS (Transport Layer Security) protocols provide secure communications over a computer network, typically between a server and client (eg. website and browser, mail server and mail client).

These protocols are based around X.509 certificates, using asymmetric cryptography (RSA) to authenticate the counter-party to communicate with and negotiate a symmetric key which is then used to encrypt the actual communications.

As a consequence of choosing X.509 certificates, certificate authorities and a public key infrastructure are necessary to verify the relation between a certificate and its owner, as well as to generate, sign, and administer the validity of certificates. While this can be more beneficial than verifying the identities via a web of trust, the 2013 mass surveillance disclosures made it more widely known that certificate authorities are a weak point from a security standpoint, allowing man-in-the-middle attacks (MITM).

The PCI Security Standards Council also recently released an official statement that all SSL versions and TLS up to v1.2 (exclusive) are now considered to be insecure protocols for payments cryptography. This means that implementations not meeting this requirement will also need to provide migration plan to the safer versions to become compliant with PCI:DSS audit and any such deployment won't be able to pass an audit after June 2016.

In the Internet Protocol Suite, TLS and SSL encrypt the data of network connections in the application layer. In OSI model equivalences, TLS/SSL is initialized at layer 5 (session layer) and works at layer 6 (presentation layer). The session layer has a handshake using an asymmetric cipher in order to establish cipher settings and a shared key for that session; then the presentation layer encrypts the rest of the communication using a symmetric cipher and that session key. In both models, TLS and SSL work on behalf of the underlying transport layer, whose segments carry encrypted data. 

How are keys and certificates exchanged?

Communication between a Server and Client starts with an initial configuration exchange, followed by sharing of their certificates. Each party provides its own certificates, usually signed by a shared certificate authority. There is nothing sensitive in this communication up until now so it carries in a plain text (green lines on a picture below).

After the certificate validation, both sides compute their pre-master secrets from random numbers provided by the other side. Client's pre-master secret is then encrypted with Server public key (received in Server certificate) and returned to encrypted to Server. This message is followed by a message signature for previous message. At this stage both sides can calculate their Master Secret which then serves as a key for data exchange.

What key length should be used?

PCI Security Standards Council claims that 1024-bit keys become likely to be crackable some time between 2006 and 2010. In regards of  2048-bit keys, those are considered safe until 2030. An RSA key length of 3072 bits should be used if security is required beyond 2030.

For example the Industry standards set by the Certification Authority/Browser (CA/B) Forum require that certificates issued after January 1, 2014 MUST be at least 2048-bit key length.

Following table just summarizes the above:

Key length Validity
1024-bits 2006-2010
2048-bits until 2030
3072-bits over 2030

SSL certificates support in BP-CCalc

EFTlab's Cryptographic Calculator (BP-CCalc) now comes with a initial draft of functionalities to support work with SSL (and other) certificates. The generate keys screen allows to generate RSA key pair (private and public keys) with appropriate lengths and optional pass phrase input.
