Secret management


In an application, we need to handle a variety of secret/secure data in the form of API keys, other application passwords, and more. Often, for an application deployed and running in a production environment, keeping these in plain text can result in security breaches. With automation up for grabs quite cheaply nowadays, for modern applications, storing such data securely with access control and secure storage is a must.

Encryption is something that has been widely embraced, but for decryption, a key needs to be circulated, and this circulation of the key is usually a big problem. If a person decides to take the key outside of the organization, there can be serious problems.

Vault from HashiCorp is a very strong contender as a solution to this issue, and helps in managing these secrets easily with very rigid controls. It provides APIs that give access based on set policies. It also has the capability to provide access control, and it also comes with encryption functionality...
