Subject: [PATCH] Add support for digests detected from ECC certificates
|
|
|
6af263 |
|
|
|
6af263 |
Previously, the digest could be detected on RSA certificates only. This
|
|
|
6af263 |
patch adds detection for ECC certificates.

[ bvanassche: changed _htmap2 into a two-dimensional array and renamed _htmap2
|
|
|
6af263 |
back to _htmap ]
