Applying a cryptographic hash or a cipher-based transformation (e.g., using a salt or a specific constant).
In the context of the Ukrainian Ministry of Finance, "instruktsiia" often refers to the official procedural manuals for the Systema Logica AIS, which manages budget processes. A "key transformation" here would involve the technical process of re-encrypting or updating digital keys used for secure interbank payment operations. instruktsiia key transformation
Recent research in Ukraine discusses digital transformation of public services using distributed ledger technology (blockchain) . In these systems, "key transformation" is the process of generating public keys from private keys using elliptic curve cryptography, governed by specific state security "instructions". Typical Steps in a Key Transformation "Instruction" it likely details these phases:
