How do I sign and verify a message on my local machine?

How do I sign a random hash value with the private key of a ton address?

If someone claims that a signature was generated by using the private key of a public key to sign a message, how do I verify the signature?

Any string which was sign by secret key can be verify with public key. Some examples below

For sign a payload (nacl used from ton-crypto)

const signatureData = beginCell()
      .storeUint(123, 32)
      .storeCoins(toNano(123))
      .endCell()
nacl.sign(signatureData.hash(), YOUR_SECRET_KEY)

For check signature on another side (js) it can be like this:

  return nacl.sign.detached.verify(message, signature, pubkey)

OR if you want to check it in contract

			(int public_key) = load_data()
      slice ref = in_msg~load_ref().begin_parse();
      var signature = ref~load_bits(512);
      int is_valid = check_signature(slice_hash(in_msg), signature, public_key)
