使用2048位java进行DES加密和解密

Is there any way of encryption and decryption using DEC/ECB 2048 bit and can we generate 2048 bit key using DES. I found that DES supports 64 bit, AES support 256 bits and If you want 2048 bit we can use RSA encryption and decryption. Also, I know that we use triple DES but it supports 168-bit encryption and decryption. Is there any way of encryption and decryption u
