REPEATING-KEY XOR LAB

Payload / Data Bytes:

XOR Key (repeats across bytes):

CRYPTOGRAPHY PRINCIPLE: XOR IS NOT SECURE BY ITSELFCRYPTOGRAPHY WARNING: XOR is a foundational symmetric mathematical operator (C = P ^ K, and P = C ^ K), but repeating-key XOR is NOT cryptographically secure. Because the key repeats cyclically, it is susceptible to Kasiski examination, Hamming-distance key-length recovery, and frequency analysis. XOR achieves perfect secrecy (Information-Theoretic Security) ONLY as a true One-Time Pad (OTP), where the key is truly random, never reused, and as long as the plaintext.

IPV4 ADDRESS & CIDR SUBNET CALCULATOR

IPv4 Address (e.g. 192.168.1.100 or 10.0.0.1/16):

Subnet Prefix:/24

/0 (Internet)/24 (Class C)/32 (Host)

Parent network prefix (contains this subnet):

/

Counts subnets of /24 inside the selected parent network.

Parent prefix must be between /0 and the subnet prefix /24.
