NSX - how to tell what version of OpenSSL is in play for LB?

[vmmed1]

My security team is asking me to tell them what version of Open SSL we're using in the load balancer.

How can I find that?

[Luke Hoffer]

On the download site for the NSX version in question on my.vmware.com there'll be an "open source" tab that you can select and there you'll find a .txt file that lists all the open source software/licenses used in NSX (including OpenSSL and the applicable version).

That did it. Thanks!

HI this can be helpful for you and I believe is more than accurate answer to your question

"3rd Party Hardware / Software products for NSX

Cryptographic Functionality:

NSX uses the following cryptographic modules when in FIPS mode:

In NSX 6.4.0 Release:

• OpenSSL 1.0.2n (VMware OpenSSL FIPS Object Module 2.9), BouncyCastle FIPS 1.0.0,

Linux Kernel v4.4 (NSX OS 4.4), Apple OS X CoreCrypto Module v5.0

Prior to NSX 6.4.0 Release:

• OpenSSL 1.0.2(p to l), BouncyCastle FIPS 1.0.0, Mozilla NSS 3.23 (VMware NSS

Cryptographic Module 3.23), Linux Kernel (v3.13 and 3.14), Apple OS X CoreCrypto

Module v5.0

Different version of OpenSSL version were used prior to 6.4.0 release. Latest version in NSX

6.2 SW release train is 6.2.9, which uses 1.0.2j. Similarly, latest version in NSX 6.3 SW

release train is 6.3.5 which uses OpenSSL version 1.0.2l.

VIX communication uses older version of OpenSSL so it is not allowed when FIPS mode is

enabled.

OpenSSL, Mozilla NSS, and Linux crypto routines are configured to use Intel AES-NI when it

is available. AES-NI is an extended set of functionality available on certain Intel and AMD

processors, which allows offloading some cryptographic operations from software to the

processor.

All crypto, except Apple CoreCrypto are open-source components, primarily maintained by

non- profit foundations. Although VMware has support agreements, commercial licenses

are not required in order to use these components."

Where do you find that information Dmitri?

:smileyhappy:

you can find it here, if not here, in NSX manager it self or in the Edge.
