In this statement, there is an expression of “decryption instructions”, which is originally created by the Japanese sentence meaning “We will tell you a way of the decryption”. This word “decryption” is a noun in Japanese as well, but easily converted to a verb as it is. If they are not familiar with the word “decryption”, they should mention rather “decrypting instruction”. This “decryption” possesses a meaning of the present participle in this statement, implying it is used as a verb in their communication frequently.
The bottom line is “decryption” is used as a noun and verb in Japanese, or “decrypt” and “decrypting” is not used in Japanese language system, once “decryption” got a dominance, as it can be used as a noun and verb.
The word of “decryption” is often used by engineers of encrypted communication. The decryption key is a necessary component to read an encrypted message. Although, there are other types of people who are familiar with this word, which are criminals committing a ransomware. They hack the corporate server, which is encrypted not to be read. Then, they ask the management to pay a ransom to get a decryption code.
In this occasion, the word “decryption” is used in Japanese well, saying “We will tell you a way of decryption, once the payment is confirmed”. That is why they used “decryption instructions”, indicating they are Japanese criminals of the ransomware.
