crypto.sha256(text)

Returns SHA-256 hash as 64-character lowercase hex digest.

use crypto
print(crypto.sha256("hello"))

crypto.base64Encode(text) / crypto.base64Decode(encoded)

Encode or decode Base64 (RFC 4648).

use crypto
let encoded = crypto.base64Encode("Hello World")
print(encoded)                     # SGVsbG8gV29ybGQ=
let decoded = crypto.base64Decode(encoded)
print(decoded)                     # Hello World

crypto.aesEncrypt(data, key, iv) / crypto.aesDecrypt(data, key, iv)

AES-256 encrypt and decrypt. Key must be 32 bytes, IV must be 16 bytes.

use crypto
let key = crypto.sha256("my-password")
let iv = bytes.bytesToHex(bytes.alloc(16))
let encrypted = crypto.aesEncrypt("secret data", key, iv)
print(encrypted)
let decrypted = crypto.aesDecrypt(encrypted, key, iv)
print(decrypted)  # secret data
