bug

2个回答

传过来的keys是否是24位秘钥,但是一些实现支持16字节密钥,其中前8个字节在场景后“自动重复”。
public static byte[] encrypt3DESECB(byte[] keyBytes, byte[] dataBytes) {
try {
if (keyBytes.length == 16) { // short key ? .. extend to 24 byte key
byte[] tmpKey = new byte[24];
System.arraycopy(keyBytes, 0, tmpKey, 0, 16);
System.arraycopy(keyBytes, 0, tmpKey, 16, 8);
keyBytes = tmpKey;
}
SecretKeySpec newKey = new SecretKeySpec(keyBytes, "DESede");

            应该就可以了

不知道你传入的keys是什么,按照你的写法,应该是base64的,但是长度够么?如果不是base64,而是字符串,那么用

new DESedeKeySpec(keys.getBytes());
