SHA256 Algorithm not showing on ASA ver 9.1

[snahosany]

Hello,

I recently installed a certificate from a thawte everything seems to work fine, except that it is still using AES-SHA1 as cipher, and in the SSL settings section in ASDM, i dont see any SHA256. Although the certificate is fully SHA256.

The ASA ver is 9.1 model 5525.

Any help would be much apprecaited.

Thanks

Hello,

If you installed a sha2 certificate it doesn't mean it will enable sha2 ciphers.

AES-256 with SHA-2 ciphers applies only to TLS version 1.2

TLSv1.2 is available in release 9.3(2) of the ASA on 5500-X models.

Please rate, thanks.
