package bytesrw

v0.3.0 2025-11-04 Zagreb

• Add the Bytesrw_sysrandom module for operating system provided cryptographically secure pseudorandom byte streams and an entropy primitive.
• Add the optional Bytesrw_crypto.Psa module for low-level cryptographic operations on byte slices. These are thin and safe bindings to the PSA Crypto API specification currently provided by the TF-PSA-Crypto C library distributed with Mbed TLS.
• Add the optional Bytesrw_crypto module for higher-level cryptographic operations implemented over Bytesrw_crypto.Psa. Mostly hashing for now. Use this if you need SHA-3 hashes.
• Add the optional Bytesrw_tls a module for TLS encrypted streams and the needed X.509 certificate management (including system lookups for trusted CAs). The backend is provided by the Mbed TLS C library.
• Add Bytesrw_unix.bytes_writer_of_socket_fd which shutdowns the fd in the send direction when the end of stream is written.
• Add Bytes.Slice.last.
• Review Int_val vs Long_val in C bindings. Affects Bytesrw_blake3, Bytesrw_md, Bytesrw_xxh, Bytesrw_zlib, Bytesrw_zstd

v0.2.0 2025-07-25 Zagreb

• Fix Bytesrw_xxhash.Xxh64.{to_hex,pp}. Leading zeros were not being printed (#5).
• Change unuseful signature of Slice.break: do not return None if any of Slice.take or Slice.drop does. Simply return the result of both operations.
• Fix wrong bound checks in Slice.{sub,make}[_or_eod]. The functions now behave like Bytes.sub as far as indexing is allowed. Thanks to Adrián Montesinos González for the report and suggesting the fix (#4).
• bytesrw.* libraries are made to export bytesrw.
