Re: Can I configure squid5 with Boring SSL

[vinod mg <vinod9987@xxxxxxxxx>]

Hi Alex,

Thanks for confirming this, it saved me lot of time :)

The reason why I wanted to try build squid5 with BoringSSL is - 

1) Current squid build with OpenSSL is not showing transactional ciphers while browsing via chrome eg: (TLS_GREASE_DA), (TLS_GREASE_IS_THE_WORD_BA)  --> is there any way to add these?

2) I am unable to supress Named group 'secp521r1' while going via this squid build on chrome browser. --> Is there any way to supress this?

I am using - https://browserleaks.com/ssl and https://www.howsmyssl.com to check above parameters.

I am using below configs with OpenSSL and it works fine except for above mentioned issues.

Hello Vinod,

    Squid does not support BoringSSL, and we will not add such support
in the foreseeable future. We have more than enough troubles with GnuTLS
support and not enough resources to support a yet another TLS library,
especially the one that is not meant for general use[1]!

[1] https://boringssl.googlesource.com/boringssl/
Although BoringSSL is an open source project, it is not intended for
general use, as OpenSSL is. We don't recommend that third parties depend
upon it. Doing so is likely to be frustrating because there are no
guarantees of API or ABI stability.


HTH,

Alex.
