How can I change the hash algorithm from MD5 to SHA1 ?
Actually my certificate was generated as RSA with MD5, which is insecure, and I have to change it to RSA with SHA1.
I changed the line "default_md = md5" to "default_md = sha1" in these files: /opt/zimbra/conf/zmssl.cnf and /opt/zimbra/conf/zmssl.cnf.in.
After this I tried to create a new cert, but didn't change.
Thanks in advance,
