Worried about sensitive data leaks? Our Blowfish encryption and decryption tool uses a symmetric-key block cipher algorithm to mitigate security risks during data transmission and storage, outputting either encrypted ciphertext or decrypted plaintext. Blowfish is a variable-key-length block cipher that utilizes a Feistel network and dynamic S-boxes to ensure highly efficient and secure data protection.
What is the key length range for Blowfish?
The key length ranges from 4 to 56 bytes, ensuring customizable security strength.
How do I fix garbled text during decryption?
Check if the secret key is correct, ensure the input and output encodings match, and verify data integrity.
The secret key must be kept confidential and remain consistent for both processes. Input and output encodings must match to prevent garbled text. While online tools are convenient, they carry inherent transmission risks; we recommend processing highly sensitive data offline.
Enhance Security: Use a strong key combination of 16 bytes or more. Example input: text "hello", key "secret123", encrypted Base64 output "U2FsdGVkX18=".
