Keystore
A Keystore is like a secure digital safe that mobile app developers use to protect sensitive information in their applications. It's particularly important in Android app development, where it stores security certificates and passwords that prove an app is authentic and hasn't been tampered with. Think of it as a digital signature that validates the app's identity, similar to how a passport proves someone's identity. When recruiters see this term in resumes, it usually indicates that the candidate has experience with app security and the official app publishing process.
