ESTREAM Portfolio
As of September 2011 the following ciphers make up the eSTREAM portfolio:
| Profile 1 (software) | Profile 2 (hardware) |
|---|---|
| HC-128 | Grain |
| Rabbit | MICKEY |
| Salsa20/12 | Trivium |
| SOSEMANUK |
These are all free for any use. Rabbit was the only one that had a patent pending during the eStream competition, but it was released into the public domain in October 2008.
The original portfolio, published at the end of Phase 3, consisted of the above ciphers plus F-FCSR which was in Profile 2. However, cryptanalysis of F-FCSR led to a revision of the portfolio in September 2008 which removed that cipher.
