 - `getFile`, `putFile`, `deleteFile`, `listfiles` now include error info upon failure.
 - `getFile` can now decrypt using a custom private key
+- Several cryptographic operations now use the native Web Crypto APIs when available. This primarily
+increases the performance of file encryption and decryption, and account seed phrase encryption and
