Hai,
We are currently testing Mongo CSFLE using C++ for our project. We’re using MongoDB 4.4 version. Previously, we faced challenges while encrypting data with CSFLE in C++ Code. Now, we want to decrypt the latest encrypted data through Mongo Shell. However, we are facing the error HMAC data authentication failed. We’re using the right Customer Master Key & Data Encryption Key as we’ve cross checked.
We’re storing the Master Key locally and importing it into Mongo Shell Environment using command mongo --eval "var LOCAL_KEY = '$MASTER_KEY'" --shell -u Admin
Defined autoEncryptionOpts as
var autoEncryptionOpts =
{
"keyVaultNamespace" : "keyvault.datakeys",
"bypassAutoEncryption" : true,
"kmsProviders" : { "local" : { "key" : BinData(0, LOCAL_KEY) } }
}
When we query the encrypted Collection using the MongoClient with CSFLE options only. We’re getting this
And, we’re able to decrypt the documents from Code. Unable to do it via Mongo Shell.
Please look into it and help us to solve this issue.
