# [−][src]Trait mundane::public::rsa::RsaKeyBits

The bit length of an RSA key.

The `RsaPrivKey`

and `RsaPubKey`

types take a `B: RsaKeyBits`

type
parameter indicating the key's length in bits.

We only support bit lengths of 2048 or greater, as smaller bit lengths are considered insecure. If 2048 is considered insecure at some point in the future, then we will remove support for it, which will be a breaking change.
