Subject: Raise default crypto algorithms to AES256 and SHA256.
X-Git-Tag: import-tinc-1.1~592^2~4
X-Git-Url: https://git.meshlink.io/?a=commitdiff_plain;h=4bb3793e38b7c7f24dd308801e7f6dbb02cf02d2;p=meshlink

Raise default crypto algorithms to AES256 and SHA256.

In light of the recent improvements of attacks on SHA1, the default hash
algorithm in tinc is now SHA256. At the same time, the default symmetric
encryption algorithm has been changed to AES256.
