DESCRIPTION

     For more details on KeyNote, see RFC 2704.

KEY GENERATION

     "keynote keygen" creates a public/private key of size KeySize, (in bits)
     for the algorithm specified by AlgorithmName.  Typical keysizes are 512,
     1024, or 2048 (bits). The minimum key size for DSA keys is 512 (bits).
     Supported AlgorithmName identifiers are:

     ‘‘dsa-hex:’’

     ‘‘dsa-base64:’’

     ‘‘rsa-hex:’’

     ‘‘rsa-base64:’’

     ‘‘x509-hex:’’

     ‘‘x509-base64:’’

     Notice that the trailing colon is required. The resulting public key is
     stored in file PublicKeyFile.  Similarly, the resulting private key is
     stored in file PrivateKeyFile.  Either of the filenames can be specified
     to be ‘‘-’’, in which case the corresponding key(s) will be printed in
     standard output.

     The optional parameters print-offset and print-length specify the offset
     from the beginning of the line where the key will be printed, and the
     number of characters of the key that will be printed per line.
     print-length includes AlgorithmName for the first line and has to be
     longer (by at least 2) than AlgorithmName.  print-length also accounts
     for the line-continuation character (backslash) at the end of each line,
     and the doublequotes at the beginning and end of the key encoding.
     Default values are 12 and 50 respectively.

ASSERTION SIGNING

     "keynote sign" reads the assertion contained in AssertionFile and
     generates a signature specified by AlgorithmName using the private key
     stored in PrivateKeyFile.  The private key is expected to be of the form
     output by "keynote keygen".  The private key algorithm and the
     AlgorithmName specified as an argument are expected to match. There is no
     requirement for the internal or ASCII encodings to match.  Valid
     AlgorithmName identifiers are:

     ‘‘sig-dsa-sha1-hex:’’

     ‘‘sig-dsa-sha1-base64:’’

     ‘‘sig-rsa-sha1-hex:’’

     ‘‘sig-rsa-sha1-base64:’’

     ‘‘sig-rsa-md5-hex:’’

     ‘‘sig-rsa-md5-base64:’’

     ‘‘sig-x509-sha1-hex:’’

     ‘‘sig-x509-sha1-base64:’’

     Notice that the trailing colon is required.  The resulting signature is
     printed in standard output. This can then be added (via cut-and-paste or
     some script) at the end of the assertion, in the Signature field.

     The public key corresponding to the private key in PrivateKeyFile is
     expected to already be included in the Authorizer field of the assertion,
     either directly or indirectly (i.e., through use of a Local-Constants
     attribute). Furthermore, the assertion must have a Signature field (even
     if it is empty), as the signature is computed on everything between the
     KeyNote-Version and Signature keywords (inclusive), and the AlgorithmName
     string.

     If the -v flag is provided, "keynote sign" will also verify the newly-
     created signature using the Authorizer field key.

     The optional parameters print-offset and print-length specify the offset
     from the beginning of the line where the signature will be printed, and
     the number of characters of the signature that will be printed per line.
     print-length includes AlgorithmName for the first line and has to be
     longer (by at least 2) than AlgorithmName.  print-length also accounts
     for the line-continuation character (backslash) at the end of each line,
     and the doublequotes at the beginning and end of the signature encoding.
     Default values are 12 and 50 respectively.

SIGNATURE VERIFICATION

     "keynote sigver" reads the assertions contained in AssertionFile and
     verifies the public-key signatures on all of them.

QUERY TOOL

     For each operand that names a file, "keynote verify" reads the file and
     parses the assertions contained therein (one assertion per file).

     Files given with the -l flag are assumed to contain trusted assertions
     (no signature verification is performed, and the Authorizer field can
     contain non-key principals.  There should be at least one assertion with
     the POLICY keyword in the Authorizer field.

     The -r flag is used to provide a comma-separated list of return values,
     in increasing order of compliance from left to right.

     Files given with the -e flag are assumed to contain environment variables
     and their values, in the format:

            varname = "value"

     varname can begin with any letter (upper or lower case) or number, and
     can contain underscores.  value is a quoted string, and can contain any
     character, and escape (backslash) processing is performed, as specified
     in the KeyNote RFC.

     The remaining options are:

     -h      Print a usage message and exit.

     -k file
             Add a key from file in the action authorizers.

     Exactly one -r and least one of each -e, -l, and -k flags should be given
     per invocation. If no flags are given, "keynote verify" prints the usage
     message and exits with error code -1.

     "keynote verify" exits with code -1 if there was an error, and 0 on
     success.
