crypt.encrypt

Encrypts Lua string bytes with AES CBC, ECB, or CTR using a Base64-decoded key, then returns Base64 ciphertext and the IV result.

Syntax

crypt.encrypt(data: string, key: string, iv?: string, mode?: "CBC" | "ECB" | "CTR" | "AES-CBC" | "AES-ECB" | "AES-CTR"): string | string | nil

Arguments

Name	Type	Required	Description
`data`	`string`	Yes	Plaintext bytes read from a Lua string.
`key`	`string`	Yes	Base64 key decoded before it is passed to AES.
`iv`	`string`	No	Optional Base64 IV for CBC or CTR. When omitted for CBC or CTR, a new AES block-size IV is generated.
`mode`	`"CBC" \| "ECB" \| "CTR" \| "AES-CBC" \| "AES-ECB" \| "AES-CTR"`	No	AES mode. The AES- prefix is removed when present. Defaults to AES-CBC. CBC and ECB use crypto library DEFAULT_PADDING; CTR uses no padding.

Returns

Name	Type	Description
`ciphertext`	`string`	Base64-encoded ciphertext.
`initializationVector`	`string \| nil`	Base64-encoded IV for CBC and CTR; nil for ECB.

Example

Encrypt a Lua string and decrypt the returned ciphertext with the returned IV.

local key = crypt.generatekey()
local ciphertext, iv = crypt.encrypt("hello world", key)

local plaintext = crypt.decrypt(ciphertext, key, iv)

print(ciphertext)
print(iv)
print(plaintext)
