 ## Description
 
@@ -19,11 +21,11 @@
 
 Ansible-Vault is very similar to Rapid Vaults. Both are streamlined and easy to use ad-hoc encryption and decryption tools. The two primary differences are that Rapid Vaults has a Ruby API instead of a Python API and that Rapid Vaults offers additional verification and defense layers. The API can also be considered similar to the high level recipes provided by PyCA's Cryptography.
 
 ### Non-Comparative Software
 
-Rapid Vaults is not similar to tools like RbNaCl or Hashicorp's Vault. RbNaCl offers advanced encryption techniques by providing bindings to libsodium. Rapid Vaults relies upon AES-256-GCM (OpenSSL) or GPG's algorithms (RSA, SHA-512, etc.). Hashicorp's Vault is Enterprise level software with many powerful features and conveniences. Rapid Vaults is a lightweight and narrowly focused tool.
