Example
const Blowfish = require('egoroof-blowfish');
const bf = new Blowfish('super key', Blowfish.MODE.ECB, Blowfish.PADDING.NULL); // only key isn't optional
bf.setIv('abcdefgh'); // optional for ECB mode; bytes length should be equal 8
const encoded = bf.encode('input text even with emoji 🎅');
const decoded = bf.decode(encoded, Blowfish.TYPE.STRING); // type is optionalYou can play with this example in runkit: https://runkit.com/egoroof/blowfish-example
Block cipher mode of operation
https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation
Blowfish.MODE.ECB // (default) Electronic Codebook
Blowfish.MODE.CBC // Cipher Block ChainingPadding
http://www.di-mgt.com.au/cryptopad.html
Blowfish.PADDING.PKCS5 // (default) Pad with bytes all of the same value as the number of padding bytes
Blowfish.PADDING.ONE_AND_ZEROS // Pad with 0x80 followed by zero bytes
Blowfish.PADDING.LAST_BYTE // Pad with zeroes except make the last byte equal to the number of padding bytes
Blowfish.PADDING.NULL // Pad with zero (null) characters
Blowfish.PADDING.SPACES // Pad with spacesReturn type
Which type of data should return method decode:
Blowfish.TYPE.STRING // (default) String
Blowfish.TYPE.UINT8_ARRAY // Uint8Array
