stream-crypto-psr7
==================

[](#stream-crypto-psr7)

PSR-7 stream decorators for WhatsApp-like media encryption.

The package provides:

- `Frista28\StreamCryptoPsr7\Stream\EncryptingStream` for PSR-7 stream encryption
- `Frista28\StreamCryptoPsr7\Stream\DecryptingStream` for PSR-7 stream decryption with MAC validation
- `Frista28\StreamCryptoPsr7\Crypto\MediaCrypto` for lower-level string and stream APIs
- `Frista28\StreamCryptoPsr7\Crypto\MediaType` for media-specific HKDF context selection

The crypto core processes source streams in chunks instead of loading the full payload into a single PHP string. The decorators materialize the transformed result into a seekable temporary stream on first read, so the exposed PSR-7 stream remains rewindable and seekable after transformation.
