Signature
A mechanism by which a server verifies the legitimacy and integrity of a request. The client generates a signature through parameter concatenation and hashing or encryption algorithms, and the server recalculates and compares it; commonly used for API security verification.
Timeline (last 90 days)
The core mechanism of signatures is that the client concatenates the parameters according to agreed rules and then computes a hash or encrypted string, and the server recomputes it using the same rules and compares the results.
Signatures are usually bound to a timestamp and are time-sensitive, requiring recomputation after they expire.
Some platforms layer risk-control fields on top of the signature mechanism, making the signature logic more complex.
A private key is the core of control over a blockchain account; holding the private key allows one to sign transactions and thereby transfer assets; giving a private key to a language model is extremely dangerous because the model may be subject to prompt injection, unauthorized invocation, or exploitation by a malicious toolchain.
