$ ENCRYPT /AUTHENTICATE NEWFILE HAMLET/CONFIRM

      Associates a MAC with the file NEWFILE using the key HAMLET.
      This command also displays a confirmation request before each
      authentication.

  $ ENCRYPT/AUTHENTICATE/UPDATE *.* MYKEY
  %ENCRYPT-NEWDB, new authentication code database has been created
  %ENCRYPT-NEWSECDB, new authentication security settings database has been created
  %ENCRYPT-I-SUMMARY1, Summary:  Files successfully authenticated: 0
  %ENCRYPT-I-SUMMARY2,     Files failing authentication: 0
  %ENCRYPT-I-SUMMARY3,     Files not in database: 73
  %ENCRYPT-I-SECSUMM1, Summary:  Security settings authenticated: 0
  %ENCRYPT-I-SECSUMM2,     Security settings failing authentication: 0
  %ENCRYPT-I-SECSUMM3,     Security settings not in database: 73

      This example creates a MAC for each file in the current
      directory using the key named MYKEY, storing them in the two
      databases: SYS$LOGIN:ENCRYPT$MAC.DAT and ENCRYPT$SEC_MAC.DAT.

  $ ENCRYPT /AUTHENTICATE *.* MYKEY
  %ENCRYPT-I-NOUPDATE, database will not be updated with new authentication codes
  %ENCRYPT-I-SUMMARY1, Summary:   Files successfully authenticated: 73
  %ENCRYPT-I-SUMMARY2,     Files failing authentication: 0
  %ENCRYPT-I-SUMMARY3,     Files not in database: 0
  %ENCRYPT-I-SECSUMM1, Summary:   Security settings authenticated: 73
  %ENCRYPT-I-SECSUMM2,     Security settings failing authentication: 0
  %ENCRYPT-I-SECSUMM3,     Security settings not in database: 0

      This example authenticates the same files as in Example 3
      by creating a new MAC and comparing that with those in each
      database, testing file data integrity and security attributes
      as indicated in the summary.

  $ ENCRYPT/CREATE_KEY/AES MY_AES_KEY32 -
  _$ "Sample Key length greater than > 32"
  $ ENCRYPT/AUTHENTICATE FILE.TXT MY_AES_KEY32 /AES=AES256 /UPDATE
  %ENCRYPT-I-NEWDB, new authentication code database has been created
  %ENCRYPT-I-NEWSECDB, new authentication security settings database has been created
  %ENCRYPT-I-SUMMARY1, Summary:   Files successfully authenticated: 0
  %ENCRYPT-I-SUMMARY2,            Files failing authentication: 0
  %ENCRYPT-I-SUMMARY3,            Files not in database: 1
  %ENCRYPT-I-SECSUMM1, Summary:   Security settings authenticated: 0
  %ENCRYPT-I-SECSUMM2,            Security settings failing authentication: 0
  %ENCRYPT-I-SECSUMM3,            Security settings not in database: 1

      This example creates new 256 bits AES key. This new key is used with
      the /AES qualifier to create new MAC database and update it with
      a 256 bits MAC value of FILE.TXT file.
