EnricoMi opened a new pull request, #47339: URL: https://github.com/apache/arrow/pull/47339
### Rationale for this change Passing encryption keys to Parquet via strings is insecure. Users are encouraged to use the `SecureString` based methods introduced in #46017 instead. To enforce this migration, deprecated methods are removed. ### What changes are included in this PR? Remove deprecated string-based methods. ### Are these changes tested? Existing Parquet encryption tests. ### Are there any user-facing changes? C++ user code that passes encryption keys to Parquet is affected and has to be adjusted. Python user code is not affected. **This PR includes breaking changes to public APIs.** -- This is an automated message from the Apache Git Service.
