CryptographicFields.cryptography module¶

exception CryptographicFields.cryptography.LengthError(length)[source]¶: Bases: Exception

CryptographicFields.cryptography.get_key(settings) → str[source]¶

Gets the encryption for encrypting & decrypting data.

Gets value from CRYPTOGRAPHIC_KEY & if not defined then from SECRET_KEY Checks the len of the key id less than 50 then raise LengthError

Raises: LengthError – It raises when the len of Encryption is less than 50 chars
Returns: Key for cryptography
Return type: str

CryptographicFields.cryptography.type_check(string) → bytearray[source]¶

Checks weather the inputed data is in correct format which is required for encryption & decryption.

Checks weather the inputed data is in correct format which is required for encryption & decryption. Which is in this case is bytearray

CryptographicFields.cryptography.to_hex(string) → hex[source]¶

Converts bytes to hex

Converts the bytes received after encryption to hex for storing it in database

CryptographicFields.cryptography.from_hex(hexstring) → bytearray[source]¶

converts hex to bytearray

Converts the hex string received from databse to bytes for decryption

CryptographicFields.cryptography.encrypt(string) → hex[source]¶

Encrypts the data

Encrypts the data recieved from user using AES-256 CFB

CryptographicFields.cryptography.decrypt(hexstring) → bytearray[source]¶

Decrypts the data

Decrypts the data recieved from database using AES-256 CFB
