Data Processing

Data processing utility functions, including encryption, decryption, and format conversion functions.

Functions

encryption

Encrypts a string using a specific algorithm.

import { encryption } from 'strap-trousers'

const encrypted = encryption('sensitive data')
console.log(encrypted) // Encrypted string

Parameters:

• str (string): String to be encrypted

Returns:

• string: Encrypted string

decrypt

Decrypts an encrypted string.

import { decrypt } from 'strap-trousers'

const encrypted = encryption('sensitive data')
const decrypted = decrypt(encrypted)
console.log(decrypted) // 'sensitive data'

Parameters:

• str (string): Encrypted string

Returns:

• string: Decrypted string

Usage Examples

Basic Encryption and Decryption

import { encryption, decrypt } from 'strap-trousers'

const originalText = 'Hello World'
const encrypted = encryption(originalText)
const decrypted = decrypt(encrypted)

console.log('Original:', originalText)
console.log('Encrypted:', encrypted)
console.log('Decrypted:', decrypted)

Practical Application

import { encryption, decrypt } from 'strap-trousers'

// Encrypt sensitive data before sending
function sendSecureData(data) {
  const encryptedData = encryption(JSON.stringify(data))
  return fetch('/api/secure-endpoint', {
    method: 'POST',
    body: encryptedData,
  })
}

// Decrypt received data
function receiveSecureData(encryptedData) {
  const decryptedData = decrypt(encryptedData)
  return JSON.parse(decryptedData)
}

Notes

• The encryption and decryption functions use the built-in formatString function for string format conversion
• For detailed format conversion rules, please refer to the String Processing Tools documentation
• These functions are suitable for simple data encryption scenarios. For high-security requirements, please use professional encryption libraries
