+# About
+
+This contains test resources for the unit tests. The file are extracted from the Minecraft directory with slight
+modifications. The files are found in `$MINECRAFT_HOME$/profilekeys/`, where `$MINECRAFT_HOME$` represents the
+OS-dependent minecraft folder.
+
+**Notable the files in this folder do not contain the private key information. It should be explicitly
+stripped before including it.**
+
+## Minecraft folder
+
+* Windows: `%appdata%\.minecraft`
+* Linux: `/home/username/.minecraft`
+* Mac: `~/Library/Application Support/minecraft`
+
+## Directory structure
+
+* `invalid_wrong_expiration.json`: Changed the expiration date
+* `invalid_wrong_key.json`: Modified public key while keeping the RSA structure valid
+* `invalid_wrong_signature.json`: Changed a character in the public key signature
+* `valid_public_key.json`: Extracted from actual file
+
+## File content
+
+* `expires_at`: Expiration date
+* `key`: Public key from the original file out of `public_key.key`
+* `signature`: Mojang signed signature of this public key

+
+This contains test resources for the unit tests. Files in this folder include pre-made cryptographic signatures.
+
+## Directory structure
+
+* `valid_signature.json`: Extracted using packet extract from actual authentication
+* `incorrect_nonce.json`: Different nonce token simulating that the server expected a different token than signed
+* `incorrect_salt.json`: Salt sent is different to the content signed by the signature (changed salt field)
+* `incorrect_signature.json`: Changed signature
+
+## File content
+
+* `nonce`: Server generated nonce token
+* `salt`: Client generated random token
+* `signature`: Nonce and salt signed using the client key from `valid_public_key.json`
