I am trying to revise the grammar of someone who insists that the following sentence is correct
In Cryptology, encryption is the process of encoding messages or information, and there are different methods, levels, and types of encryptions
His rationale is that it's a noun, and nouns can be pluralized. It feels wrong, and I want to modify that to say the following: (more edits are needed)
In cryptology, encryption is the process of encoding messages or information, and there are different methods, levels, and types of encryption formats
where the final word is formats, schemes, systems ..but then I realized that there probably several modifiers that I would use after the word encryption.
Question
- Is it ever acceptable to use the word "encryptions"
- When using a phrase such as "encryption ____", what are acceptable plural words and their meanings?
