SHA-1 fingerprint of keystore certificate

Getting the SHA-1 Fingerprint of a Keystore Certificate 📜🔒

Have you ever encountered this confusing question - "Is the method for getting an SHA-1 fingerprint the same as the method of getting the fingerprint?" 🤔 Well, worry not, because we are here to clarify this for you! 🎉

Understanding the Basics 🧐

First things first, let's quickly understand what a SHA-1 fingerprint and a keystore certificate are. The SHA-1 fingerprint is a unique 160-bit cryptographic hash value that acts like the digital "fingerprint" of a keystore certificate. It is widely used for certificate validation and security purposes. On the other hand, a keystore certificate is a secure container for cryptographic keys and certificates.

Common Confusion 😓

Now, let's address the confusion raised by our fellow developer 🚀. They were running a command on the Windows Command Prompt using the keytool.exe tool to obtain a fingerprint. However, they were unsure if the result they were getting is the SHA-1 fingerprint.

👉 The command they used:

keytool -list -v -keystore keystore.jks

Clarification, Please! 🕵️‍♀️

To clarify things, the result obtained via the keytool command does represent the SHA-1 fingerprint of the keystore certificate. The -list option displays detailed information about the certificates stored in the keystore, including the SHA-1 fingerprint.

Easy Solution! 🎯

To make your life even easier, if you want to extract only the SHA-1 fingerprint without the additional information, just modify the command a little bit:

keytool -list -v -keystore keystore.jks | findstr SHA1

This modified command uses the findstr command in Windows to filter the output and display only the line containing "SHA1" (i.e., the SHA-1 fingerprint of the keystore certificate).
