Security is paramount, especially when handling sensitive documents. pypdf supports both RC4 and AES encryption. However, developers are strongly advised to use AES algorithms, as RC4 is considered insecure. The library also supports AES-256-R5 for the highest level of security and implements SASLprep (RFC 4013) for standardizing passwords, ensuring better cross-platform compatibility.

The bytecode interpreter dynamically analyzes running code and replaces generic opcodes with type-specific operations. If a specific loop repeatedly adds two integers, Python optimizes that exact byte operation. In version 12, this specialization covers more opcodes, reducing execution time for math-heavy and string-heavy applications. Micro-Optimizations and Memory Footprint this specialization covers more opcodes
