Hello, Please help to understand the cryto algorithms used for :
1) HDFS encryption at rest
2) SSL/TLS communications
We have a HDP 2.5
Hi @Vishal Gupta the following crypto algorithms are used:
1) HDFS Encryption at rest uses AES/CTR/NoPadding as the cipher suite. The key size can be 128 or 256 bits.
2) The SSL/TLS question is a bit more difficult to answer as it depends on the individual components involved, however everything is covered in this chapter of our documentation:
3) Kerberos itself is a protocol, I suggest you take a look at https://en.wikipedia.org/wiki/Kerberos_(protocol)
I hope that helps!
