I want to encrypt messages sent via AS2 receiver adapter. There are multiple algorithms supported by CPI. We want to use 3DES.
1. What key length is used by SAP for 3DES? Is it 168 bits? There is no option to provide key length except RC2 algorithm.
2. We also need to provide Public Key alias.
Where can we generate this? In keystore, when i try create key-pair, i dont see the option apart from RSA, DSA and EC.
As per my understanding 3DES is symmetric algorithm using 3 keys. How do we provide keys to receiver system too so that they can decrypt messages?
