Decrypt a short AES sample
Input
secret123 Base64 encrypted text
Output
hello world
Useful for reversing an AES-encrypted sample.
Developer Tools
Review practical AES Decrypt examples so you can understand expected input, output, and common patterns faster.
Use this AES Decrypt tool to reverse AES-encrypted Base64 text using the original passphrase. It is useful for browser-side decryption tests, reversible development workflows, encrypted sample validation, and confirming that AES-encrypted values can be decoded back into readable text correctly.
Example pages are especially useful for developer tools because they show what good input looks like, what kind of output to expect, and how the tool behaves in common scenarios.
Input
secret123 Base64 encrypted text
Output
hello world
Useful for reversing an AES-encrypted sample.
Input
demo-key Base64 encrypted text
Output
{"name":"John","role":"admin"} Useful for checking that encrypted structured text returns correctly.
Fix: Use the exact same passphrase that was used during encryption.
Fix: Paste valid Base64 ciphertext produced by the matching AES encrypt workflow.
Fix: Put the passphrase first and the ciphertext below it.
Fix: This usually means the passphrase or ciphertext format is wrong.
Fix: Use the matching decrypt tool for the actual cipher.
After reviewing these examples, run the live tool with your own input. If your task involves a follow-up step, the related page can help you move to the next tool in the workflow.
