Documentation

Overview

Package storage is designed to securely store the most sensitive information (keys, passwords).

STORAGE ALGORITHM 'CREATE'

1. 	S = G(N)
	where
		G - generator pseudo random bytes,
		N - count of bytes for generator,
		S - pseudo random bytes (salt).
2. 	K = KDF(P, S)
	where
		KDF - key derivation function
		K - encryption key,
		P - password,
3.	EM = E(K, VM)
	where
		E - encryption function,
		EM - encrypted map/storage,
		VM - void map/storage.

STORAGE ALGORITHM 'SET'

1. 	M = D(K, EM)
	where
		D - decryption function
		M - map/storage
2. 	Km = KDF(Ki, S)
	where
		Km - key map/storage
		Ki - input key
3. 	Vm = E(Km, Vi)
	where
		Vm - value map/storage
		Vi - input value
4. 	M = SET(H(Km), Vm)
	where
		H - hash function
		SET - set H(Km),Vm to map/storage
5. 	EM = E(K, M)

STORAGE ALGORITHM 'GET'

1. 	M = D(K, EM)
	where
		M - map/storage
2. 	Km = KDF(Ki, S)
	where
		Km - key map/storage
		Ki - input key
3. 	Vm = GET(H(Km))
	where
		GET - get Vm from map/storage by Km
4. 	Vi = D(Km, Vm)

STORAGE ALGORITHM 'DEL'

1. 	M = D(K, EM)
	where
		D - decryption function
		M - map/storage
2. 	Km = KDF(Ki, S)
	where
		Km - key map/storage
		Ki - input key
3. 	M = DEL(H(Km))
	where
		DEL - delete Vm from map/storage by Km
4. 	EM = E(K, M)
