func ComputeSharedSecret

func ComputeSharedSecret(pub string, sec string) (secret []byte, e error)

ComputeSharedSecret computes an Elliptic Curve Diffie Hellman shared secret out of one public key and another secret key.

The public key and secret key for this can be either hex or bech32 formatted, since this is easily determined by reading the first 4 bytes of the string

func Decrypt

func Decrypt(content string, key []byte) ([]byte, error)

Decrypt decrypts a content string using the shared secret key. The inverse operation to message -> Encrypt(message, key).

func Encrypt

func Encrypt(message string, key []byte) (string, error)

Encrypt encrypts message with key using aes-256-cbc. key should be the shared secret generated by ComputeSharedSecret.

Returns: base64(encrypted_bytes) + "?iv=" + base64(initialization_vector).
