tf = crypto.ed25519.verify(filename, signature, publicKey, '-file')
| Parameter | Description |
|---|---|
| message | a uint8 vector (raw bytes) or a character vector (UTF-8 bytes): signed content. |
| filename | a string: existing file whose raw bytes are the signed content. |
| signature | a uint8 vector of 64 bytes or 128 hexadecimal characters. |
| publicKey | a uint8 vector of 32 bytes or 64 hexadecimal characters. |
| '-file' | first argument is a filename. |
| Parameter | Description |
|---|---|
| tf | a logical: true if the signature is valid for the message and the public key. |
crypto.ed25519.verify checks a pure Ed25519 signature (RFC 8032, section 5.1) over the exact bytes of a message.
An invalid signature returns false without raising an error. Signatures produced by crypto.ed25519.sign or by any RFC 8032 implementation (for example openssl pkeyutl -sign -rawin) are accepted.
The public key is the raw 32-byte Ed25519 key, given as bytes or as lowercase or uppercase hexadecimal text.
