onetime - 1.122-1 main

OneTime is an encoder/decoder that uses the one-time pad algorithm.
.
OneTime is a simple one-time pad encryption program that takes care
of some of the pad-management bureaucracy for you. It avoids
re-using pad data (except when decrypting the same encrypted message
twice, of course) by maintaining records of pad usage.
.
If you keep your ~/.onetime configuration area under version control
with Subversion or CVS, OneTime will automatically update it to get
the latest pad usage records before using a pad, and will commit new
records after using a pad. Thus, by sharing a single configuration
area via version control, you and your interlocutors can more easily
avoid the sin of pad range reuse.
