Buffers have the following size constraints:

pk: 64 bytes, corresponding to the "raw" representation of an elliptic curve point (see Point representation and conversions)
sk, k: 32 bytes
signature: 64 bytes
msg: no size requirement for variants using SHA-2 hashing (see ECDSA)

Sourcetype bytes = SharedDefs.CBytes.t

Sourceval sign : sk:bytes -> msg:bytes -> k:bytes -> bytes option

sign sk msg k attempts to sign the message msg with secret key sk and signing secret k and returns the signature if successful.

Sourceval verify : pk:bytes -> msg:bytes -> signature:bytes -> bool

verify pk msg signature checks the signature of msg using public key pk and returns true if it is valid.

Sourcemodule Noalloc : sig ... end
