Using libsodium securely in mobile applications

Key lifecycles, signatures, encryption and application data.

Keys and cryptography1 min readEditorial methods

libsodium offers high-level cryptographic options. Mobile integrations also depend on binding maintenance and native-library versions.

Evaluation approach

Follow official API contracts for keys, nonces and verification. Language bindings must preserve those properties.

Application example

A native verification failure must not become success when passed to Dart or JavaScript.

Limits and considerations

Bindings sharing a library name do not necessarily share quality or maintenance status.

Why binding upgrades matter

Bridges can change error types and memory behavior. Record both bridge and native versions, and verify that authentication failures remain failures in the upper layer.

Checks and decisions

  • Review bindings
  • Test error propagation
  • Pin versions
