How to verify signature of a signed message in PHP?

I’m currently trying to verify a signed message with Phantom in PHP but I haven’t found any resources. If anyone can explain me the theory of cryptography or knows a package to do this, I would be very happy!

[SOLVED]: Verifying NFC chip signature

I am attempting to verify a signature from an NFC chip using this program. Here is an example of the signature it emits:

{
  "input": {
    "keyNo": 1,
    "digest": "bcf83051a4d206c6e43d7eaa4c75429737ac0d5ee08ee68430443bd815e6ac05",
    "message": "010203"
  },
  "signature": {
    "raw": {
      "r": "93137bc7bfeaa86e26c6a9bbd6fb8acdf73ed5fd232cc2be1a0714f583f04d2e",
      "s": "7f5d7c2461daf8649587c3c510fce05a74146cbe79341427065d0d878d154a1b",
      "v": 27
    },

  },
  "publicKey": "046ca7458b4c8c4f9a196094bda5f01ac1e588f6604bc2f7a58ba4d1fa3c3cb9102720bdb43f73972ea3dfc1c6ab8a6cb7d14114765eb76ff0fb2df34a5f7cab56",
  "etherAddress": "0x1aaBF638eC3c4A5C2D5cD14fd460Fee2c364c579"
}

is it possible to verify this signature using this program?
if so, can you provide a test case that does verify it?

Thank you in advance for the help!

Wallet adapter signMessage

The signature of MessageSign on the wallet adapter differs from @noble/ed25519. Would you happen to have any idea?

[SOLVED]: Why can't we verify through a CPI?

After read your check_ed25519_data function, I wonder, Isn't it suffice to do verify {msg, signature, pubkey} without IX data ? To my expecience on Ethereum, we can recover public key from signature, and compare it agaist pubkey
Your Tx compose from 2 instructions, first one is sig verification IX. I think this first IX do verification also, then, why do we need to check sig again in second IX ?

Can you help me with this issue? https://solana.stackexchange.com/questions/5604/how-to-send-message-and-signature-as-vecu8-and-u8-64-to-program . The way you create instruction isn't used anymore. Tks
