# This is an example chrony keys file. It is used for NTP authentication with # symmetric keys. It should be readable only by root or the user to which # chronyd is configured to switch to. # # Don't use the example keys! The keys need to be random for maximum security. # These shell commands can be used to generate random MD5 and SHA1 keys on # systems which have the /dev/urandom device: # echo "1 MD5 HEX:$(tr -d -c '[:xdigit:]' < /dev/urandom | head -c 32)" # echo "1 SHA1 HEX:$(tr -d -c '[:xdigit:]' < /dev/urandom | head -c 40)" # Examples of valid keys: #1 ALongAndRandomPassword #2 MD5 HEX:B028F91EA5C38D06C2E140B26C7F41EC #3 SHA1 HEX:1DC764E0791B11FA67EFC7ECBC4B0D73F68A070C
