Historically, English forms nouns from verbs using -or more often than -er when referring to tools or agents in technical contexts. This is why:
- Encrypt → Encryptor
- Decrypt → Decryptor
Over time, decrypter appeared as a natural variation, but it never replaced decryptor as the dominant form.

Both words function as:
- Nouns
