Beginner here. How can I access an encrypted bucket. I read the documentation and it doesnt clearly state how will I create an encrypted bucket besides the default encryption option and bucket policy. I cant use a KMS key for the encryption
I checked this AWS Server-Side Encryption C# but I dont know where I will get the following
ServerSideEncryptionCustomerMethod =AES256
ServerSideEncryptionCustomerProvidedKey=base64(secretkey)
ServerSideEncryptionCustomerProvidedKeyMD5 : md5(base64(secretkey))
Could you please simplify or discuss the steps.

I am trying to write a prisma policy to ensure s3glacier has logging and encryption enabled. However l donot see an arguement in the terraform code for these two checks. Does glacier inherit these from s3 automatically? Thank you
I tried using the glacier sns topic present for logging but l still cannot figure out how to check for encryption.
I am storing data in file in aws s3 and already enabled SSE. but i am curious to know is there a way to encrypt the data so when someone download the file so they cant see the content?? I am just new to AWS and it would be great if somw one give the input
Use the AWS Key Management Service (AWS KMS) to encrypt the data prior to uploading it to an Amazon S3 bucket. Then the data will remain encrypted until it's decrypted using the key. YOu can find an example here (for Java SDK)
https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/javav2/example_code/s3/src/main/java/com/example/s3/KMSEncryptionExample.java
already enabled SSE.
SSE encrypts the content on S3, but an authenticated client cloud access the content in plain, the encryption is done under the hood and the client is unable to access the ciphertext (encrypted form)
You can use the default s3 key or a custom KMS key (CMS) , where the client need explicit access to decrypt the content.
download the file so they cant see the content??
Then the content needs to be encrypted before the upload. AWS provides some support for the client-side encryption but the client is free to implement its own encryption strategy and the key management.
To solve trouble with managing the keys on the client side, it's often more practical to stick with SSE and allow access to S3 or the used CMS (key) only to identities that must access the content.
I know we can select a KMS (customer or AWS managed) key when creating our RDS database.
However I find the documentation quite vague about the different processes so I've got the following questions:
Does it mean that only one datakey will be used for the whole database to encrypt everything ?
Where exactly is the encrypted version of the data key located ?
When does RDS decrypt the encrypted datakey to use it ?
How often does RDS need to make an API call against KMS to decrypt the encrypted version of the data key it keeps ?
Does it mean that only one datakey will be used for the whole database
The documentation really doesn't specify any details. Based on the aws best practices and other documentation I'd assume the data key is cached and reused for certain time and then regenerated.
However the details are not publicly available. All the storage encryption is hidden under the hood and not visible to the client
How often does RDS need to make an API call against KMS to decrypt the encrypted version of the data key it keeps ?
AWS KMS calls are logged in the CloudTrail and you will see the calls on the bill as well. At least for the CMK (I'm not sure how is it for the default service KMS).
I need to encrypt plain text passwords and other sensitive information using AWS KMSin nodejs server. Is it possible with AWS KMS.
I am new to AWS KMS i don't have much info about AWS KMS. Please suggest solution for this.
Thanks
Has anybody tried to use AWS KMS on Heroku?
On one hand, Heroku runs on AWS, so presumably it should work.
On other hand, I haven't seen any references that it was used in Heroku.
My main goal is to be able to get an encryption key from a hardware secure module (vs hardcoding it in my code or putting it in an environmental variable).
There is no reason why you should not be able to call a KMS endpoint from anywhere you have internet connectivity.
You still need to have an access key and secret access key for the AWS account you are using and that account needs to have permissions on KMS.
You will need to distribute the encrypted stuff and the aws keys to your Heroku instance. You can then decrypt and use KMS from there.
One thing that it worth mentioning: when using KMS you never see the actual key KMS uses. You can create the key, you can encrypt and decrypt, and/or you can have permissions on the specific API operations, but you cannot get the plaintext key.
What you normally do is some sort of envelope encryption in which you generate your own key and encrypt it via KMS and send the encrypted key and the encrypted data to the destination.
