Functions

func DecryptData

func DecryptData(data io.Reader, decryptionKey []byte) io.Reader

DecryptData decrypts data using AES-GCM with nonce (4KB size).

func EncryptData

func EncryptData(data io.Reader, encryptionKey []byte) io.Reader

EncryptData encrypts data using AES-GCM with nonce (4KB chunks).

func GeneratePBEKey

func GeneratePBEKey(password string, salt []byte) []byte

GeneratePBEKey generates a 32-byte encryption key for PBE with salt. This key is used to encrypt/decrypt user files uploaded to the server. The key itself is stored in the keyring.

func GenerateRandomNBytes

func GenerateRandomNBytes(n int) ([]byte, error)

GenerateRandomNBytes generates a random byte slice of length n.
