AES Encryption Mode Comparator

Compare performance and security of different AES encryption modes (ECB, CBC, CTR, GCM)

Pattern Type

Repeating 16-byte blocks - shows ECB weakness clearly

Data Size: 100 KB (100 KB)

Benchmark Configuration

ECB (Electronic Codebook)InsecureServer-only

Encrypts each block independently. NOT SECURE - reveals patterns in data.

CBC (Cipher Block Chaining)

Each block depends on previous block. Secure but not authenticated.

CTR (Counter Mode)

Turns block cipher into stream cipher. Secure but not authenticated.

GCM (Galois/Counter Mode)Recommended

Authenticated encryption. Most secure - includes integrity checking.

ECB mode is cryptographically insecure and included only for educational purposes. It reveals patterns in encrypted data.

More iterations = better statistical accuracy
