pyUmbral is a Python implementation of David Nuñez's threshold proxy re-encryption scheme: Umbral_.
Implemented with OpenSSL_ and Cryptography.io_, pyUmbral is a referential and open-source cryptography library
extending the traditional cryptological narrative of "Alice and Bob" by introducing a new actor,
*Ursula*, who has the ability to take secrets encrypted for Alice and *re-encrypt* them for Bob,
without being able to learn any information about the original secret.
pyUmbral is the reference implementation of the Umbral_ threshold proxy re-encryption scheme.
It is open-source, built with Python, and uses OpenSSL_ and Cryptography.io_.
Using Umbral, Alice (the data owner) can *delegate decryption rights* to Bob for
any ciphertext intended to her, through a re-encryption process performed by a
set of semi-trusted proxies or *Ursulas*. When a threshold of these proxies
participate by performing re-encryption, Bob is able to combine these independent
re-encryptions and decrypt the original message using his private key.
