SSH RSA 生成使用

package main

import (
    "fmt"
    "encoding/pem"

    "github.com/deatil/lakego-filesystem/filesystem"

    cryptobin_ssh "github.com/deatil/go-cryptobin/ssh"
    cryptobin_rsa "github.com/deatil/go-cryptobin/cryptobin/rsa"
)

func main() {
    fs := filesystem.New()

    rsa := cryptobin_rsa.NewRsa().GenerateKey(2048)

    // block, _ := cryptobin_ssh.MarshalOpenSSHPrivateKey(rsa.GetPrivateKey(), "comment")
    // block, _ := cryptobin_ssh.MarshalOpenSSHPrivateKeyWithPassword(rsa.GetPrivateKey(), "comment", []byte("123"))
    rsaBlock, _ := cryptobin_ssh.MarshalOpenSSHPrivateKeyWithPassword(
        rsa.GetPrivateKey(),

        []byte("123"),
        cryptobin_ssh.Opts{
            // cryptobin_ssh.AES256CBC
            Cipher:  cryptobin_ssh.AES256CTR,
            KDFOpts: cryptobin_ssh.BcryptOpts{

    rsaBlockkeyData := pem.EncodeToMemory(rsaBlock)

SSH RSA 解析使用

package main

            CreatePKCS8PrivateKey().
            ToKeyString()

        fs.Put("./ssh-key/rsa-key-pkcs8", sshRsaPriKey)

        fmt.Println("解析 key 成功")
        fmt.Println("证书 comment 为: " + comment)
    } else {
        fmt.Println("解析 key 失败，错误信息为: " + err.Error())
    }
}

SSH 生成公钥

package main

import (
    "fmt"

    "github.com/deatil/lakego-filesystem/filesystem"

    "github.com/deatil/go-cryptobin/ssh"
    cryptobin_rsa "github.com/deatil/go-cryptobin/cryptobin/rsa"
)

func main() {
    fs := filesystem.New()

    sshRsaPubKey := cryptobin_rsa.New().
        GenerateKey().
        GetPublicKey()

    sshPubKey, _ := ssh.NewPublicKey(sshRsaPubKey)
    sshAuthorizedKey := ssh.MarshalAuthorizedKeyWithComment(sshPubKey, "abc@email.com")

    fs.Put("./ssh-key/pub/rsa.pub", string(sshAuthorizedKey))

	fmt.Println("生成公钥成功")
}
