tsrpc 框架flows中间件 的加密解密算法 及ase 对称加密算法Ts

// 发送前加密
server.flows.preSendDataFlow.push(v => {
    v.data= EncryptUtil.encrypt(JSON.stringify(v.data));
    return v;
});

// 接收前解密
server.flows.preRecvDataFlow.push(v => {
    v.data= EncryptUtil.decrypt(JSON.stringify(v.data));
    console.log(v.data);
    return v;
})

 

 // 发送前加密
    this.client.flows.preSendDataFlow.push(v => {
        let en=new EncryptUtil();
        v.data=en.encrypt(JSON.stringify(v.data));
        return v;
    });

    // 接收前解密
    this.client.flows.preRecvDataFlow.push(v => {
        let en=new EncryptUtil();
        v.data=en.decrypt(v.data);
        return v;
    })

Uint8Array加密算法1，

加密 各个字节-1

解密 各个字节+1

export class EncryptUtil {

    // 加密
    encrypt(data: string): Uint8Array {
        const buf=this.stringToUint8Array(data)
        for (let i = 0; i < buf.length; ++i) {
            buf[i] -= 1;
        }
        return buf;
    }

     // 解密
    decrypt(data:any): Array<JSON> {
        let buf;
        if(typeof data =="string"){
            const arr_data=JSON.parse(data)
            buf=arr_data.data
        }else if(typeof data =="object"){
            buf=new Uint8Array(data)
            
        }
        buf=new Uint8Array(buf)
        for (let i = 0; i < buf.length; ++i) { 
            buf[i] += 1;
        }
        const nk=this.Uint8ArrayToString(buf)
        const result=JSON.parse(nk)
        return result;
    }

    //uint8array 转 string   
    Uint8ArrayToString(fileData:Uint8Array):string{
        let dataString = "";
        for (let i = 0; i < fileData.length; i++) {
        dataString += String.fromCharCode(fileData[i]);
        }
        return dataString
    }
  
    //string 转 uint8array
    stringToUint8Array(str:string):Uint8Array{
        const arr = [];
        for (let i = 0, j = str.length; i < j; ++i) {
            arr.push(str.charCodeAt(i));
        }
        const tmpUint8Array = new Uint8Array(arr);
        return tmpUint8Array
    }
    //object-uint8array 转uin8array

}
