crypt.encrypt

Symmetric encryption. mode defaults to CBC.

Syntax

crypt.encrypt(data: string, key: string, iv?: string, mode?: string) -> string

Parameters

Parameter	Type	Description
`data`	`string`	The data payload to process or send.
`key`	`string`	The key or secret used by the operation.
`iv?`	`string`	The iv value used by the call.
`mode?`	`string`	The cipher mode to use.

Returns

Type	Description
`string`	The returned string.

Description

crypt.encrypt is part of the Crypt library. Crypt functions process data locally. Keys, hashes and encrypted buffers remain inside the process.

The operation is performed immediately using the arguments supplied at the call site.

The aliases crypt.decrypt(data, key, iv, mode?) resolve to the same implementation.

Example

local key = crypt.generatekey(32)
local iv = crypt.generatebytes(16)
local encrypted = crypt.encrypt("secret", key, iv, "CBC")
print(crypt.decrypt(encrypted, key, iv, "CBC"))

Notes

Aliases: crypt.decrypt(data, key, iv, mode?).
Never log keys or decrypted buffers in production scripts.
