Design of cryptographic primitives (algorithms), like block ciphers, stream ciphers, random-number generators, hash functions, MACs, key exchanges, public-key encryption or signature schemes. Also tag with the relevant type of primitive. If you ask about a known existing algorithm, also tag with its name.

Can I safely replace XOR with ADD in a stream cipher?
consider you have a key $K$ and plaintext $P$.
then,
$P \oplus K = C$ (cipertext)
$C \oplus K = P$ (plaintext)
Here, algorithms for encryption and decryption are same (thats not true for addition) …
