Crypto Module Documentation

The crypto module provides various cryptographic functionalities, including hashing and encryption/decryption.

Functions

md5(input)

Generates an MD5 hash for the given input.

  • input: The data to hash (byte array).

Returns the MD5 hash as a hexadecimal string.

sha1(input)

Generates a SHA-1 hash for the given input.

  • input: The data to hash (byte array).

Returns the SHA-1 hash as a hexadecimal string.

sha256(input)

Generates a SHA-256 hash for the given input.

  • input: The data to hash (byte array).

Returns the SHA-256 hash as a hexadecimal string.

sha512(input)

Generates a SHA-512 hash for the given input.

  • input: The data to hash (byte array).

Returns the SHA-512 hash as a hexadecimal string.

sha3_256(input)

Generates a SHA3-256 hash for the given input.

  • input: The data to hash (byte array).

Returns the SHA3-256 hash as a hexadecimal string.

AES (crypto.aes)

The aes module provides functionalities for AES encryption and decryption.

AES Functions

encrypt(plaintext, key)

Encrypts the given plaintext using the specified key.

  • plaintext: The data to encrypt (byte array).
  • key: The encryption key (byte array).

Returns the encrypted data as a byte array.

decrypt(ciphertext, key)

Decrypts the given ciphertext using the specified key.

  • ciphertext: The data to decrypt (byte array).
  • key: The decryption key (byte array).

Returns the decrypted data as a byte array.

block_size

The block size of the AES cipher.

Example Usage

import "crypto"

// Hashing examples
md5hash := crypto.md5("example_data")
println(md5hash)
