Kerberos Encryption Type Numbers

Registration Procedure(s)
Standards Action for standards-track RFCs; non-standards-track 
RFCs must be reviewed by an expert.
Expert(s)
Ken Raeburn
Reference
[RFC3961]
Note
These are signed values ranging from -2147483648 to 2147483647.  Positive
values should be assigned only for algorithms specified in accordance
with this specification for use with Kerberos or related protocols.
Negative values are for private use; local and experimental algorithms
should use these values.  Zero is reserved and may not be assigned.
