AES-128 Encryption/Decryption support in Vertica 9.0
Does Vertica 9.0 support AES Decryption using a key natively?
I am ingesting data into Vertica that has column values that have been encrypted in different system (Hive) using a key.
I have the key, however am not able to decrypt using the key in Vertica.
I tried encryption_package from Vertica-Extension-Packages on github.
I can provide additional details, if required.
Thanks in advance.

Hi, and apologies for not seeing this sooner. My guess is that the encryption support in the C++ UDF in Vertica-Extensions is not quite the same as what is used by Hive, where our C++ UDF example is eight years old and limited in options while Hive uses the javax.crypto package.
My guess is that you'd need to implement a Java UDF derived from the AesBase and AesDecrypt classes that Hive uses. These can be found at https://github.com/apache/hive/tree/master/ql/src/java/org/apache/hadoop/hive/ql/udf/generic in the GenericUDFAesBase.java and GenericUDFAesDecrypt.java classes.
Thanks much Bryan,
My turn to apologize for not seeing your response sooner. It all worked out at the customer site as they started using encrypted values for analytics/reporting. They just encrypted the specific columns all the respective tables before feeding to Vertica.
Thanks much for your help though. I'll pursue this as some cycle permits.
Thx.
