critical issue about QNX need for help

I am using QNX IPsec setkey. Seems QNX only support SHA1.

Does QNX IPsec support SHA256?
I checked the manual for IPsec and found no information.


Thanks a lot in advance!

Re: critical issue ... {SHA-256 supported?}

SHA-2 is a generic reference to: SHA-224, SHA-256, SHA-384, SHA-512.

Those are HMAC algorithms indicated as arguments to the function setkey (the utility to “Manually manipulate the IPsec 
SA/SP database”).

Please look for the section “Algorithms for protocol” in the page.

Parameter <aalgo> is indicated as two different parameters of setkey. See the parameters for authentication and 
encryption:

-A aalgo key
    Specify an authentication algorithm (aalgo) for the ah ...
-E ealgo key
    Specify an encryption algorithm (ealgo) for the esp ...

All of the SHA-2 appear to be there for Authentication.
