bls for eth with compiled static library

This repository contains compiled static library of https://github.com/herumi/bls with BLS_ETH=1.

• SecretKey; Fr
• PublicKey; G1
• Sign; G2

News

• 2021/Jan/28 (change specification) enable VerifySignatureOrder and VerifyPublicKeyOrder by default
• 2021/Jan/28 (change specification) verify returns false for zero public key
• 2021/Jan/02 support arm64 golang on M1 mac
• 2020/Oct/15 add SecretKey::GetSafePublicKey(), which returns an error if sec is zero
• 2020/Oct/08 MultiVerify returns true only if all signatures are valid.
• 2020/Sep/18 static binary for x64 is JIT-less mode, which uses code pre-generated by Xbyak.
• 2020/Jul/03 remove old tests and use the latest hash function defined at draft-07 is set by default.
• 2020/May/22 SignHashWithDomain, VerifyHashWithDomain, VerifyAggregateHashWithDomain are removed.
• 2020/May/15 EthModeDraft07 is added for draft-07.
• 2020/Apr/20 EthModeDraft06 is default. Call SetETHmode(EthModeDraft05) to use older evrsion.
• 2020/Mar/26 The signature value in SetETHmode(2) has changed because of changing DST in hash-to-curve function.
• 2020/Mar/17 This library supports eth2.0 functions. But the spec of hash-to-curve function may be changed.

Init as the followings:

Init(BLS12_381) 

then, you can use the following functions.

The size of message must be 32 byte.

Check functions:

• VerifySignatureOrder ; make deserialize check the correctness of the order
• Sign::IsValidOrder ; check the correctness of the order
• VerifyPublicKeyOrder ; make deserialize check the correctness of the order
• PublicKey::IsValidOrder ; check the correctness of the order
• AreAllMsgDifferent ; check that all messages are different each other

How to run examples/sample.go

go get github.com/ninjahome/bls-eth-go-binary/ go run examples/sample.go 

How to build the static library

The following steps are not necessary if you use compiled binary in this repository.

Linux, Mac, Windows(mingw64)

git clone --recursive https://github.com/ninjahome/bls-eth-go-binary # git submodule update --init --recursive cd bls-eth-go-binary make CXX=clang++ go test ./bls -bench "Pairing|Sign|Verify" 

clang generates better binary than gcc.

Android

make android 

iOS

make ios 

How to cross-compile for armeabi-v7a

Check llc --version shows to support the target armv7a.

make ../mcl/src/base32.ll env CXX=clang++ BIT=32 ARCH=arm _OS=android _ARCH=armeabi-v7a make MCL_USE_GMP=0 UNIT=4 CFLAGS_USER="-target armv7a-linux-eabi -fPIC" 

• Remark : clang++ must support armv7a-linux-eabi.

How to build sample.go for armeabi-v7a

env CC=arm-linux-gnueabi-gcc CGO_ENABLED=1 GOOS=linux GOARM=7 GOARCH=arm go build examples/sample.go env QEMU_LD_PREFIX=/usr/arm-linux-gnueabi qemu-arm ./sample 

How to cross-compile for mipsel

Check llc --version shows to support the target mips.

make ../mcl/src/base32.ll env CXX=clang++ BIT=32 ARCH=mipsel _OS=linux _ARCH=mipsle make MCL_USE_GMP=0 UNIT=4 CFLAGS_USER="-target mipsel-linux -fPIC" 

• Remark : clang++ must support mipsel-linux.

How to build sample.go for mipsel

env CC=mipsel-linux-gnu-gcc CGO_ENABLED=1 GOOS=linux GOARCH=mipsle GOMIPS=softfloat go build examples/sample.go env QEMU_LD_PREFIX=/usr/mipsel-linux-gnu qemu-mipsel ./sample 

How to use the static library from C

#define BLS_ETH #include <mcl/bn_c384_256.h> #include <bls/bls.h>

bls for eth with compiled static library

此存储库包含已编译的https://github.com/herumi/blsBLS_ETH=1。

• 秘钥；Fr
• 公钥；G1
• 符号；G2默认情况下启用VerifySignatureOrder和VerifyPublicKeyOrder（更改规范）验证零公钥返回false（更改规范）只有当所有签名都有效时，zero才会返回true。

新闻

• 2020/Sep/18 x64的静态二进制文件是无JIT模式，它使用xbyk预先生成的代码。
• 2020/Jul/03删除旧测试并使用draft-07中定义的最新哈希函数是默认设置的。
• 2020/5/22 SignHashWithDomain、VerifyHashWithDomain、VerifyAggregateHashWithDomain被删除。
• 草案07增加了2020/5/15 EthModeDraft07。
• 默认为2020/Apr/20 EthModeDraft06。调用SetETHmode（EthModeDraft05）以使用旧版本。
• 2020/Mar/26由于将哈希函数中的DST更改为曲线函数，SetETHmode（2）中的签名值已更改。
• 2020/Mar/17此库支持eth2.0函数。但是hash-to-curve函数的规范可能会改变。验证签名顺序；反序列化检查顺序的正确性；检查顺序的正确性；检查所有消息是否彼此不同
• 备注：clang++必须支持armv7a linux eabi。
• 备注：clang++必须支持mipsel linux。
• 2020/Apr/20 EthModeDraft06 is default. Call SetETHmode(EthModeDraft05) to use older evrsion.
• 2020/Mar/26 The signature value in SetETHmode(2) has changed because of changing DST in hash-to-curve function.
• 2020/Mar/17 This library supports eth2.0 functions. But the spec of hash-to-curve function may be changed.

初始化如下：

Init(BLS12_381) 

然后，可以使用以下函数。

消息大小必须为32字节。

检查函数：

• VerifySignatureOrder ; make deserialize check the correctness of the order
• Sign::IsValidOrder ; check the correctness of the order
• VerifyPublicKeyOrder ; make deserialize check the correctness of the order
• PublicKey::IsValidOrder ; check the correctness of the order
• AreAllMsgDifferent ; check that all messages are different each other

如果在此存储库中使用已编译的二进制文件，则不需要执行以下步骤。

iOS

git clone --recursive https://github.com/ninjahome/bls-eth-go-binary # git submodule update --init --recursive cd bls-eth-go-binary make CXX=clang++ go test ./bls -bench "Pairing|Sign|Verify" 

clang生成的二进制文件比gcc更好。
