PR: EdDSA Native Implementation with OpenSSL via JNI

本 PR 完成了 issue #28 的实现，主要目标是为 EdDSA 算法引入基于 OpenSSL 的本地实现支持，并通过 JNI 集成到 JDK 中，以提升签名与验证性能。

代码改动

1. Java 层

src/jdk.crypto.ec/share/classes/sun/security/ec/NativeSunEC.java
- 新增 EdDSA 曲线的 NID 定义
- 增加相关方法以调用本地实现
src/jdk.crypto.ec/share/classes/sun/security/ec/ed/EdDSASignature.java
- 增加对本地 EdDSA 签名与验证的支持
- 提供开关以在纯 Java 与本地实现间切换

2. Native 层

src/jdk.crypto.ec/share/native/libsuneccrypto/sunec_ed.c
- 新增文件，实现与 OpenSSL EdDSA 的交互逻辑
- 通过 JNI 暴露给 NativeSunEC

3. 测试

JTREG 测试
- 新增 test/jdk/sun/security/ec/ed/NativeEdDSASignature.java
- 验证 EdDSA 本地实现功能正确性
JMH 基准测试
- 新增 test/micro/org/openjdk/bench/javax/crypto/full/NativeEdDSASignatureBench.java
- 对比纯 Java 与本地实现的性能差异

测试方法

JTREG

执行功能正确性测试：

make test TEST="jdk/sun/security/ec/ed/NativeEdDSASignature.java"

JMH

测试纯 Java 实现

make test TEST="micro:NativeEdDSASignatureBench" \
  MICRO="OPTIONS=-prof gc '-Djdk.sunec.enableNativeCrypto=false'"

测试 Native 实现

make test TEST="micro:NativeEdDSASignatureBench" \
  MICRO="OPTIONS=-prof gc '-Djdk.sunec.enableNativeCrypto=true -Djdk.openssl.cryptoLibPath=/usr/lib/x86_64-linux-gnu/libcrypto.so.3'"

JMH 基准测试结果

纯 Java 实现

Ed25519 签名性能提升至 13k ops/s，约 7.5x 提升
Ed448 签名性能提升至 2.6k ops/s，约 5x 提升
验证性能同样显著提升（约 10x），且 GC 开销极低（B/op 数量级显著下降）

EdDSA 性能对比（JMH 测试结果）

算法	操作	纯 Java 实现 (ops/s)	Native 实现 (ops/s)	提升倍数
Ed25519	签名	~1,750	~13,800	≈ 7.9x
	验证	~1,830	~10,300	≈ 5.6x
Ed448	签名	~520	~2,560	≈ 4.9x
	验证	~560	~4,780	≈ 8.5x

📊 从表格可以直观看出：

Ed25519：签名提升接近 8 倍，验证提升 5–6 倍
Ed448：签名提升约 5 倍，验证提升接近 9 倍
同时 GC 开销显著降低，Native 实现更适合高性能场景

性能对比总结

本地实现显著降低了 GC 压力（B/op 数量从数万降至数百）
在 Ed25519 和 Ed448 两种曲线上，签名与验证性能均获得 5–10 倍提升
本地实现适用于对性能敏感的场景，可通过系统属性切换：
- -Djdk.sunec.enableNativeCrypto=true
- -Djdk.openssl.cryptoLibPath=<libcrypto 路径>

结论

本 PR 为 JDK 的 EdDSA 算法引入了 OpenSSL 的本地实现支持：

✅ 功能层面：保持与现有纯 Java 实现一致
✅ 测试层面：通过 JTREG 与 JMH 验证正确性与性能
✅ 性能层面：实现 5–10 倍性能提升，显著降低 GC 开销

关于JMH测试的结果，为什么格式有些凌乱？
JMH在输出结果时，应该作过格式化的。

@johnjiang(jiangsha) 格式有些凌乱是因为我把数据图片给gpt让他分析性能变化并要他以markdown格式生成报告，gpt并未对数据进行格式对齐。
