I have some very highly confidential data that i want to store in s3 bucket.
I want to make policies ( bucket or iam whatever required) in such a way that no one ( not even admin) can read the contents of files in that bucket from aws console.
But i will have a program running on my host that needs to put and get data from that s3 bucket.
Also i will be using server side encryption of s3 but i can't use client side encryption of s3.

You are looking for something like this;
"Id": "bucketPolicy",
"Statement": [
"Action": "s3:*",
"Effect": "Deny",
"NotPrincipal":
"AWS": [
"arn:aws:iam::111111111111:user/USERNAME",
"arn:aws:iam::111111111111:role/ROLENAME"
]
,
"Resource": [
"arn:aws:s3:::examplebucket",
"arn:aws:s3:::examplebucket/*"
]
],
"Version": "2012-10-17"
For test purposes make sure you replace arn:aws:iam::111111111111:user/USERNAME with your user arn. So in case you lock out everybody you can at least perform actions on the bucket.
arn:aws:iam::111111111111:role/ROLENAME should be replaced by the role arn which is attached to your EC2 instance (I am assuming that is what you mean by host).

Two problems: explicit deny cannot be overridden by explicit allow, and it is impossible to prevent the root credentials from deleting and then replacing a bucket policy, giving the root credentials a backdoor to the bucket.

@Michael-sqlbot you are correct I missed the condition in the deny statement. I shall fix it in my answer soon.

@Michael-sqlbot policy is updated. It only allows actions to the bucket for specified user/role.
