## Malleability and the `legacy_compatibility` Feature

A signature scheme is considered to produce _malleable signatures_ if a passive attacker with knowledge of a public key _A_, message _m_, and valid signature _σ'_ can produce a distinct _σ'_ such that _σ'_ is a valid signature of _m_ with respect to _A_. A scheme is only malleable if the attacker can do this _without_ knowledge of the private key corresponding to _A_.
