Short answercipher 0.5.2 has 7 features. Nothing is on by default: turn on what you use. It needs Rust 1.85 or newer.
Pick features
Every feature
| Feature | In default | Turns on |
|---|---|---|
alloc | nothing else (a switch the code checks) | |
block-padding | inout/block-padding | |
dev | blobby | |
getrandom | common/getrandom | |
rand_core | common/rand_core | |
stream-wrapper | block-buffer | |
zeroize | dep:zeroize, common/zeroize, block-buffer?/zeroize |
dep:x turns on the optional dependency x; x/y turns on feature y of dependency x (with ?, only if x is already on).
