Description Joshua Roys 2012-11-29 18:47:41 UTC 
Description of problem:
openswan does not support certificates signed with the SHA2 family


Version-Release number of selected component (if applicable):
openswan-2.6.32-19.el6_3


How reproducible:
Setup openswan with certificate authentication, certs are signed using SHA2

  
Actual results:
openswan fails to setup connection with "digest algorithm not supported"


Expected results:
openswan successfully sets up connection


Additional info:
Please apply 98e2372ccaab3c585029dede2f1f6c7240a3c354 from upstream and set USE_EXTRACRYPTO=true in the spec file.  We have tested this locally.
Comment 2 Paul Wouters 2013-05-17 18:54:58 UTC 
Note if we do port the attached patch, it should OT use EXTRACRYPTO because that also drags in support for blowfish and serpent, which we do not want.

Instead, SHA2 should be decoupled from EXTRACRYPTO, as has been done already in upstream libreswan.
Comment 3 Paul Wouters 2013-07-18 03:44:51 UTC 
for QA: to test, generate at least one X.509 certificate that uses SHA2.

For an example, see: https://github.com/libreswan/libreswan/blob/master/testing/x509/dist_certs
