MessageLock - File Encryption

MessageLock is a modern Android encryption app built to protect your text, photos, and files. It brings text encryption, text decryption, photo encryption, photo decryption, file encryption, and file decryption together in one clean experience. The goal is simple: help you protect sensitive content with a clear flow that feels fast, practical and easy to understand for simple local privacy.

The structure is straightforward. First you enter or choose your content, then you move to the password step, and finally you receive the encrypted result or the restored file on a separate result screen. This step by step design keeps the experience organized, reduces mistakes, and makes each action easier to follow. Because the result appears on its own screen, copying, sharing, reviewing, or starting another action feels more controlled.

The text encryption flow is designed to feel like writing a note. You can enter a short note, a long message, an explanation, or any text you want to protect with a password. After encryption, the output appears on a dedicated result screen where long content can be scrolled comfortably. You can copy or share the encrypted text. On the decryption side, you simply paste the encrypted content, enter the correct password, and recover the original text.

Photo encryption is built for users who want a cleaner way to protect images. You can choose a photo from the gallery or the system picker, create a password, and let the app generate an encrypted file. The same clarity continues in the photo decryption flow. Select the encrypted image file, enter the correct password, and the restored content is prepared on a separate result screen.

File encryption is designed for everyday document protection. MessageLock supports common formats such as PDF, TXT, DOCX, ZIP, and many other file types. You can use it for work files, personal archives, reports, contracts, notes, or other sensitive documents. After encryption, the app creates a secure output file. In the file decryption flow, you choose the encrypted file, enter the password, and restore the original content on a separate screen.

MessageLock follows a privacy focused approach. The content handling model is designed to work on the device so you keep more control while selecting, encrypting, and decrypting your data. This makes the app a practical choice for people who want offline protection for messages, notes, photos, and important files.

On the security side, MessageLock is built around a modern encryption approach. Text, photo, and file flows use AES-256-GCM based protection. Password based key derivation is strengthened, and unique values are generated for each action. Still, real security also depends on the strength of the password you choose, which is why the app includes a password strength indicator during the encryption flow.

MessageLock also includes practical protection features beyond the core encrypt and decrypt screens. You can lock the app with biometrics or an app PIN. You can set an automatic clipboard clear delay for copied sensitive text. If activity history is enabled, only an action summary is stored; passwords, raw content, and decrypted data are not saved. You can also turn history off completely if you prefer.

Key features:
• Encrypt and decrypt text
• Encrypt and decrypt photos
• Encrypt and decrypt files
• Step by step flows with separate result screens
