        # OpenSSL::PKey::PKey.verify

(from ruby core)
### Implementation from PKey
---
    pkey.verify(digest, signature, data [, options]) -> true or false

---

Verifies the `signature` for the `data` using a message digest algorithm
`digest` and a public key `pkey`.

Returns `true` if the signature is successfully verified, `false`
otherwise. The caller must check the return value.

See #sign for the signing operation and an example.

See also the man page EVP_DigestVerify(3).

`digest`
:   See #sign.
`signature`
:   A String containing the signature to be verified.
`data`
:   See #sign.
`options`
:   See #sign. `options` parameter was added in version 3.0.
