*** TIS/PEM Version 7.0

Much has changed in this new, improved version of TIS/PEM.

o single-user operation with executables that can be shared 
o per-user ASCII (human-readable) databases
o support for multiple databases
o support for both certificates and bare public keys
o flexible trust model
o signature, verification, encryption, and decryption services are provided
  by their own programs and functions, making integration with other mail
  user agents straightforward
o support for MIME-PEM integration
o administrative functions are handled by several scriptable applications
  and much can be done using standard text processing tools
o less reliance on UNIX-specific features
o easier installation
o faster processing

Because of the new database format, users of all versions of TIS/PEM prior
to 7.0 must export their registrations using the existing TIS/PEM cai
program if they wish to use the same certificates/key pairs in TIS/PEM 7.0.
The pemdbconv program will convert exported registrations to user records in
a database file and a private key file.

Other certificates in the TIS/PEM database can be converted to user records
in a database file by using pemdbconv to process the cfiles in the old
PEMDATA/CERTDIR directly.  This will not convert any associated private
keys, however.  Owners of private keys must convert them themselves.
