What is an ADBKEY file?

ADBKEY files mostly belong to adb. The *.adbkey file is a key file used by Android Debug Bridge for secure device authentication. It holds the private key that adb generates automatically during the debugging setup. This key pairs with a public key (often saved as an *.adbkey.pub file) to establish a trusted connection between your PC and an Android device.
If you need to inspect this file, use a text editor capable of showing plain text. Do not modify the key, as any changes may disrupt device connectivity.
Key details provided by FilExt.com include:

Used to secure adb communication.

Automatically generated and stored in the .android directory.

Follows a format similar to OpenSSH keys.

Android Debug Bridge (ADB)
.ADBKEY files store the private key used by the Android Debug Bridge (ADB) for secure communication between a computer and an Android device. These keys are part of a public-key cryptography system that ensures only authorized connections can access the device's debug interface. The .ADBKEY file itself contains the private portion of the key pair, while the corresponding public key (.ADBKEY.PUB) is stored on the Android device. When ADB attempts to connect, it uses these keys to perform an authentication handshake. This mechanism protects against unauthorized access and manipulation of the device during development and debugging. This file format is classified as Developer Files.

ADBKEY format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file).
