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.
