# Splitted Secret
|
||||||
|
The purpose of this software is to splitt a secret over multiple people. Just if a defined amount of this people meet together they can encrypt the secret and have access to it.
|
||||||
|
|
||||||
|
# Requirements to know
|
||||||
|
- Amount of People
|
||||||
|
- How much people need to reunite for decrypting
|
||||||
|
|
||||||
|
# Requirements to implement
|
||||||
|
- Plattform independend
|
||||||
|
- easy to use
|
||||||
|
|
||||||
