crypto

Hashing and encoding utilities. All functions accept and return strings.

Functions

crypto.sha256(input) -> string

Returns the SHA-256 hash of input as a lowercase hex string.

crypto.sha256("hello")
// "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"

crypto.md5(input) -> string

Returns the MD5 hash of input as a lowercase hex string.

crypto.md5("hello")
// "5d41402abc4b2a76b9719d911017c592"

Note: MD5 is cryptographically broken. Use crypto.sha256 for security-sensitive hashing. MD5 is provided for compatibility and checksums only.

crypto.base64_encode(input) -> string

Encodes input as a Base64 string using the standard alphabet.

crypto.base64_encode("hello world")
// "aGVsbG8gd29ybGQ="

crypto.base64_decode(input) -> string

Decodes a Base64 string back to its original form.

crypto.base64_decode("aGVsbG8gd29ybGQ=")
// "hello world"

crypto.hex_encode(input) -> string

Encodes input as a hexadecimal string.

crypto.hex_encode("AB")
// "4142"

crypto.hex_decode(input) -> string

Decodes a hexadecimal string back to its original form.

crypto.hex_decode("4142")
// "AB"
