- Branch encryption prevents attackers from knowing or inferring program states before they are reached.
- It protects constant data (e.g., passwords) used in comparisons by replacing them with hashed values.
- Encrypted code blocks inside conditional statements can only be decrypted with the correct input key.
- The technique combines hashing for comparison and encryption for conditional code execution.
- An example with JavaScript shows how hashing and XOR encryption can hide a password and secret message.
- Branch encryption is useful for protecting comparison values and associated code or data.
