Deploy\n\n[![Release](https://github.com/sixafter/prng-chacha/workflows/release/badge.svg)](https://github.com/sixafter/prng-chacha/actions)\n\n---\n## Overview \n\nThe `prng` package provides a high-performance, cryptographically secure pseudo-random number generator (CSPRNG) that implements the `io.Reader` interface. Designed for concurrent use, it leverages the ChaCha20 cipher stream to efficiently generate random bytes.\n\nTechnically, this PRNG is not pseudo-random but is cryptographically random.\n\nThe package includes a global `Reader` and a `sync.Pool` to manage PRNG instances, ensuring low contention and optimized performance.\n\nPlease see the [godoc](https://pkg.go.dev/github.com/sixafter/prng-chacha) for detailed documentation.\n\n---\n\n## Features\n\n* **Cryptographic Security:** Utilizes the [ChaCha20](https://pkg.go.dev/golang.org/x/crypto/chacha20) cipher for secure random number generation. \n* **Concurrent Support:** Includes a thread-safe global `Reader` for concurrent access. \n * Up to 98% faster when using the `prng.Reader` as a source for v4 UUID generation using Google's [UUID](https://pkg.go.dev/github.com/google/uuid) package as compared to using the default rand reader.\n * See the benchmark results [here](#uuid-generation).\n* **Efficient Resource Management:** Uses a `sync.Pool` to manage PRNG instances, reducing the overhead on `crypto/rand.Reader`. \n* **Extensible API:** Allows users to create and manage custom PRNG instances via `NewReader`.\n- **UUID Generation Source:** Can be used as the `io.Reader` source for UUID generation with the [`google/uuid`](https://pkg.go.dev/github.com/google/uuid) package and similar libraries, providing cryptographically secure, deterministic UUIDs using PRNG-CHACHA.\n\n---\n\n## Verify with Cosign\n\n[Cosign](https://github.com/sigstore/cosign) is used to sign releases for integrity verification.\n\nTo verify the integrity of the release tarball, you can use Cosign to check the signature against the public key.\n\n```sh\n# Fetch the latest release tag from GitHub API (e.g., \"v1.14.0\")\nTAG=$(curl -s https://api.github.com/repos/sixafter/prng-chacha/releases/latest | jq -r .tag_name)\n\n# Remove leading \"v\" for filenames (e.g., \"v1.14.0\" -\u003e \"1.14.0\")\nVERSION=${TAG#v}\n\n# ---------------------------------------------------------------------\n# Verify the source archive using Sigstore bundles\n# ---------------------------------------------------------------------\n\n# Download the release tarball and its signature bundle\ncurl -LO \"https://github.com/sixafter/prng-chacha/releases/download/${TAG}/prng-chacha-${VERSION}.tar.gz\"\ncurl -LO \"https://github.com/sixafter/prng-chacha/releases/download/${TAG}/prng-chacha-${VERSION}.tar.gz.sigstore.json\"\n\n# Verify the tarball with Cosign using the published public key\ncosign verify-blob \\\n --key \"https://raw.githubusercontent.com/sixafter/prng-chacha/main/cosign.pub\" \\\n --bundle \"prng-chacha-${VERSION}.tar.gz.sigstore.json\" \\\n \"prng-chacha-${VERSION}.tar.gz\"\n\n# ---------------------------------------------------------------------\n# Verify the checksums manifest using Sigstore bundles\n# ---------------------------------------------------------------------\n\ncurl -LO \"https://github.com/sixafter/prng-chacha/releases/download/${TAG}/checksums.txt\"\ncurl -LO \"https://github.com/sixafter/prng-chacha/releases/download/${TAG}/checksums.txt.sigstore.json\"\n\ncosign verify-blob \\\n --key \"https://raw.githubusercontent.com/sixafter/prng-chacha/main/cosign.pub\" \\\n --bundle \"checksums.txt.sigstore.json\" \\\n \"checksums.txt\"\n\n# ---------------------------------------------------------------------\n# Confirm local artifact integrity\n# ---------------------------------------------------------------------\n\nshasum -a 256 -c checksums.txt\n```\n\nIf valid, Cosign will output:\n\n```shell\nVerified OK\n```\n\n---\n\n## Verify Go module\n\nTo validate that the Go module archive served by GitHub, go mod download, and the Go\nproxy are all consistent, run the `module-verify` target. This performs a full cross-check\nof the tag archive and module ZIPs to confirm they match byte-for-byte.\n\n---\n\n## Installation\n\n```bash\ngo get -u github.com/sixafter/prng-chacha\n```\n\n---\n\n## Usage\n\n## Usage\n\nGlobal Reader:\n\n```go\npackage main\n\nimport (\n \"fmt\"\n \n \"github.com/sixafter/prng-chacha\"\n)\n\nfunc main() {\n buffer := make([]byte, 64)\n n, err := prng.Reader.Read(buffer)\n if err != nil {\n // Handle error\n }\n fmt.Printf(\"Read %d bytes of random data: %x\\n\", n, buffer)\n}\n```\n\nReplacing default random reader for UUID Generation:\n\n```go\npackage main\n\nimport (\n \"fmt\"\n\n \"github.com/google/uuid\"\n \"github.com/sixafter/prng-chacha\"\n)\n\nfunc main() {\n // Set the global random reader for UUID generation\n uuid.SetRand(prng.Reader)\n\n // Generate a new v4 UUID\n u := uuid.New()\n fmt.Printf(\"Generated UUID: %s\\n\", u)\n}\n```\n\n---\n\n## Performance Benchmarks\n\n### Raw Random Byte Generation\n\nThese `prng.Reader` benchmarks demonstrate the package's focus on minimizing latency, memory usage, and allocation overhead, making it suitable for high-performance applications.\n\n\u003cdetails\u003e\n \u003csummary\u003eExpand to see results\u003c/summary\u003e\n\n```shell\nmake bench-csprng\ngoos: darwin\ngoarch: arm64\npkg:
