Frequently Asked Questions page
Yes. Files can be encrypted and decrypted from any accessible storage device.
No. It works entirely offline.
If a file has been altered or corrupted, decryption will fail.
Yes, particularly for securely transferring or storing sensitive documents. The upcoming Pro version will further enhance business use cases.
Files are stored as an archive during encryption. When decrypted, they are extracted into a folder to preserve structure.
Within this folder you will find all the files with their original filenames – as you had them prior to encryption.
All contents are restored into a newly created folder to keep files organised and avoid overwriting.
Currently, output files are saved alongside the original for simplicity. Additional options may be added in future versions.
Not currently. The app is designed for manual use. Automation may be considered in future versions.
No. Your password is never stored or transmitted. It is only used during encryption/decryption.
It is your responsibility to store it safely. Consider using a password manager.
Bitwarden makes a free version which works well.
Yes. The MacOS version is distributed as a standard app. Future versions will support additional platforms.
No. If the process is interrupted, you will need to start again.
Decryption will fail, and the file will remain encrypted. No data is revealed. The file is undamaged and will decrypt with the correct password.
Yes. Files can be encrypted multiple times if required, though this is generally unnecessary.
No. Encryption is for security, not compression. File sizes will remain roughly the same or slightly larger.
No. Files are packaged into an archive before encryption, but not compressed. File size will remain similar to the original.
Yes. Encrypted files can be moved, copied, emailed, or stored anywhere. They can be decrypted on any system running EncryptDecrypt with the correct password.
Yes. You can rename the file, but you must keep the .edsecure extension for the app to recognise it correctly.
No. EncryptDecrypt uses modern encryption designed specifically for security. Standard ZIP password protection is weaker and not recommended for sensitive data.
Currently available for MacOS.
Windows and Linux versions are planned.
Yes. There is an option within the app to clear the log history.
The log is stored locally on your machine in the app’s working directory.
Yes. A local log is maintained showing encryption and decryption activity, along with file size before and after encryption / decryption, and the time & date.
The process will stop and the output file may be incomplete or unusable. You will need to start again.
Encryption speed depends on:
File size
Disk speed
System performance
Large files will take longer to process.
There is no fixed limit, but performance depends on your system. Large files (tens of GB) are supported but may take time.
Yes. Encrypted files can be safely shared via email or messaging platforms. The recipient will need the password to decrypt them.
All file types are supported. The app treats files as data and does not depend on file format.
Yes. Multiple files and folders can be selected and bundled into a single encrypted archive.
Encrypted files are saved in the same directory as the original file or folder.
No. Your original files and folders remain unchanged. A separate encrypted or decrypted copy is created.
No. Everything happens locally on your machine. No data is sent to the cloud.
No. If the password is lost, the data cannot be recovered. There is no reset or recovery mechanism.
Yes. The encryption used is considered strong and suitable for protecting sensitive data, provided you use a strong password that isn’t used for anything else, and you keep the password in a safe place.
EncryptDecrypt uses modern, industry-standard encryption (based on the age format) designed for strong security and simplicity.
