Module encryption 

Module that provides a simple API for symmetric encryption in the output formats used by Concordium.

Structs

CipherText

A wrapper around a byte array to represent a ciphertext. JSON encodings are in base64.

EncryptedData

Ciphertext together with metadata describing the encryption method.

EncryptionMetadata

Metadata that enables decryption of some encrypted data provided an a password is provided.

Password

A wrapper to make it less likely to abuse passwords.

Enums

DecryptionError

Errors that can occur during AES decryption.

EncryptionMethod

Supported encryption methods.

KeyDerivationMethod

Supported key derivation methods.

Constants

AES_BLOCK_SIZE

AES block size in bytes

NUM_ROUNDS

The number of rounds of the key derivation function to use for hashing the password.

Functions

decrypt

Dual to the encrypt method.

encrypt

Encrypt the given plaintext using the provided password. This uses the AES256 cipher using PBKDF2SHA256 key derivation function using a randomly sampled salt. The number of rounds of the key derivation function is defined by the NUM_ROUNDS constant.
