You can use pretty much any cipher. It's not restricted to ECB, CBC, or anything like that.
Hello
It's not about restriction its about security & purpose of use.
for example you can use most case aes-cbc-128 its simple and secure. but still there are case people use aes-ctr & aes-gcm
Almost all AES(other then ECB mode) provide good security.
There are also WhiteBox-AES CTR/CBC provide more security then standard.
Block mode and cypher aren't the same thing.
In search of someone who implemented AES encryption with the Rijndael -Algorithm. ("NIST" compliant)
Please write to me, thank you very much!
Is there a reason you want someone who can implement this vs using an existing library?
