IPSec IKEv1 tunnel, using MD5 as the algorithm in the IPSec transform set, fails to create QM keys. The following syslogs are generated: *May 3 07:27:11.202: %CRYPTO_ENGINE-3-CSDL_COMPLIANCE_FAIL: Cisco PSB security compliance violation is detected. Use of MD5 by IPSEC key engine is denied *May 3 07:27:11.202: %CRYPTO_ENGINE-3-CSDL_COMPLIANCE_FAIL: Cisco PSB security compliance violation is detected. Use of MD5 by IPSEC key engine is denied Specifically, the following shows up in debugs: *May 3 07:32:28.316: IPSEC(crypto_ipsec_create_ipsec_sas): Map found Tunnel200-head-0, 65537 *May 3 07:32:28.316: crypto_engine: Generate IKE QM keys *May 3 07:32:28.316: crypto_engine: weak algorithm MD5 not CSDL compliant *May 3 07:32:28.316: %CRYPTO_ENGINE-3-CSDL_COMPLIANCE_FAIL: Cisco PSB security compliance violation is detected.

IPSec tunnel configured with DES/3DES as the encryption algorithm or MD5 HMAC algorithm in the transform set.
Use different encryption or HMAC algorithm within the IPSec transform set.
An additional fix from CSCwb78173 is needed to completely fix this issue.
