Inferno Security Modules and Utilities
Note:
U.S. Department of Commerce and U.S. State Department
regulations restrict the export of certain security algorithms.
These restricted algorithms include DES and RC4 (with key length
greater than 40 bits). Anyone wanting to purchase Inferno with
DES and a version of RC4 supporting a key size greater than 40
bits should contact Lucent Technologies at the phone number
listed in the readme
file delivered with Inferno.
Organization of this chapter
An overview of Inferno security is found in Security Overview.
A summary of the Inferno related components of security is found in Summary of Security Modules, Commands, Daemons and Abstract Data Types.
The security modules, functions, commands and daemons are arranged in several categories as shown below. They are described in the last part of this chapter.
Authentication, Login Functions

Auth module - authenticated connections
-
auth, readauthinfo, writeauthinfo - authenticate a connection
-
getauthinfo - obtain a certificate for authentication
-
Login module - communicate with certificate authority
-
logind - login daemon
-
verify - command to authenticate receiver of blinded certificate
Password Management
-
changelogin - command to create/update the password file
-
get, put - read and write password entries in the password file
Key Management
-
certtostr, pktostr, sktostr, strtocert, strtopk, strtosk -encryption key conversion functions
-
