AES with 256 bit keys

RSA with 1024 bit keys

Detailed explanation-1: -AES 256-bit encryption is the strongest and most robust encryption standard that is commercially available today.
Detailed explanation-2: -The AES-256 key schedule transforms a 256-bit secret key into fourteen 128-bit rounds keys. Of the two, the AES-128 key schedule is actually more secure.
Detailed explanation-3: -This is important because the security of the one-time pad depends on the security of the one-time pad exchange. If an attacker is able to intercept the one-time pad value, they can decrypt messages sent using the one-time pad.
Detailed explanation-4: -AES-128 uses a 128-bit key length to encrypt and decrypt a block of messages. AES-192 uses a 192-bit key length to encrypt and decrypt a block of messages. AES-256 uses a 256-bit key length to encrypt and decrypt a block of messages.
