- o Minor features (performance, RNG):
- - Tor now constructs a fast secure pseudorandom number generator for
- each thread, to use for cases where performance is critical. This PRNG
- is based on AES-CTR, using a buffering construction similar to
- libottery and the (newer) OpenBSD arc4random() code. It outperforms
- OpenSSL 1.1.1a's CSPRNG by roughly a factor of 100 for small outputs.
- Although we believe it to be cryptographically strong, we are only
- using it when necessary for reasonable performance. Implements tickets
- 29023 and 29536.
