LOKI97 Online Encryption/Decryption

Australian Block Cipher - 128-bit block, variable key length AES candidate algorithm

Security Notice

LOKI97 was an AES candidate algorithm but was not selected as the standard. For new applications requiring high security, AES (Rijndael) is recommended.

Key Features

128-bit block size, meeting modern security standards
16-round Feistel structure ensures thorough data confusion

Encryption Mode Description

Padding

LOKI97 supports 128-bit (16 bytes), 192-bit (24 bytes), or 256-bit (32 bytes) keys.

Encryption Key

Initialization Vector (IV) (128 bit / 16 bytes)

Format Options

Documentation

This tool performs local LOKI97 block-cipher encryption/decryption with multiple modes, paddings, and encoding formats.

Key Features

LOKI97 support (128-bit block, 128/192/256-bit keys)
CBC, ECB, CFB, OFB, and RAW modes
Multiple input/output formats
Key and IV length validation

Steps

Choose encrypt or decrypt mode.
Configure mode, padding, key size, and encodings.
Enter key, IV, and input text.
Process and copy the output.

Notes

Non-ECB modes usually require a valid IV.
Keep all parameters identical for cross-system compatibility.
For new projects, broadly adopted standards such as AES are often preferred.
