`fixUnencryptedSize()` asked the encryption module for the unencrypted block size before calling `begin()`. The module only learns the encoding of the file (binary or legacy base64) from the header in `begin()`, so the block size of binary encoded files was used for legacy base64 files. This stored an inflated unencrypted size for legacy files, which then breaks downloads: the announced content length is too large and the signature check of the last block fails with "Bad Signature". Fixes #63662 Assisted-by: ClaudeCode:claude-opus-5-5 Signed-off-by: Ferdinand Thiessen <opensource@fthiessen.de>
