Go语言AES加密:ECB模式无填充加密与Base64编码

本文演示如何在Go语言中使用AES/ECB/NoPadding模式加密字符串,并进行Base64编码。 我们将解决一个实际问题:使用密钥"er2fb6ts3ecx"加密字符串"406bf0ad11310101220213481000320000",并得到Base64编码后的结果。

Go language AES encryption: How to encrypt strings and base64 encoding using AES/ECB/NoPadding mode?

问题与解决方案:

许多AES加密示例使用CBC模式和填充。然而,本例要求使用ECB模式和NoPadding。 这需要仔细处理密钥长度和潜在的填充问题。

以下Go代码实现了AES/ECB/NoPadding加密和Base64编码:

package main

 

import (

    "crypto/aes"

    "encoding/base64"

    "fmt"

    "log"

)

 

func main() {

    plaintext := []byte("406bf0ad11310101220213481000320000")

    key := []byte("er2fb6ts3ecx")

 

    ciphertext, err := encryptECB(plaintext, key)

    if err != nil {

        log.Fatal(err)

    }

 

    fmt.Printf("Ciphertext (Base64): %s\n", ciphertext)

 

 

    decrypted, err := decryptECB(ciphertext, key)

    if err != nil {

        log.Fatal(err)

    }

 

    fmt.Printf("Decrypted: %s\n", string(decrypted))

}

 

func encryptECB(plaintext, key []byte) (string, error) {

    block, err := aes.NewCipher(padKey(key))

    if err != nil {

        return "", err

    }

 

    if len(plaintext)%aes.BlockSize != 0 {

        return "", fmt.Errorf("plaintext is not a multiple of the block size")

    }

 

    ciphertext := make([]byte, len(plaintext))

    for i := 0; i

<p>这段代码包含了<code>encryptECB</code>和<code>decryptECB</code>函数,分别用于ECB模式下的AES加密和解密。<code>padKey</code>函数确保密钥长度为16字节。  由于使用NoPadding,我们不需要处理填充。  请注意,ECB模式的安全性较低,不建议在生产环境中使用。</p>

<p>这个改进后的代码更简洁,更易于理解,并且正确处理了密钥长度和NoPadding的情况。  记住,在实际应用中,选择更安全的模式(如CBC或GCM)至关重要。</p>

Understanding Go's error Interface Understanding Go's error Interface Apr 27, 2025 am 12:16 AM

Go's error interface is defined as typeerrorinterface{Error()string}, allowing any type that implements the Error() method to be considered an error. The steps for use are as follows: 1. Basically check and log errors, such as iferr!=nil{log.Printf("Anerroroccurred:%v",err)return}. 2. Create a custom error type to provide more information, such as typeMyErrorstruct{MsgstringDetailstring}. 3. Use error wrappers (since Go1.13) to add context without losing the original error message,
