RSA PKCS1和PKCS8的ASN格式

發(fā)布時間：2023/12/20 编程问答 38 豆豆

生活随笔收集整理的這篇文章主要介紹了 RSA PKCS1和PKCS8的ASN格式小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

最近要和支付寶支付做個對接，然后發(fā)現(xiàn)自己對RSA一無所知。。。。補(bǔ)知識點(diǎn)吧。。。。

嗯，百度了一下Sha256withRSA，出現(xiàn)了一大堆文章，嗯，都很好，學(xué)習(xí)中。。。。。

然后，將支付寶提供的測試密鑰導(dǎo)入到c#，出現(xiàn)問題了，一直失敗，好吧，c#的證書格式和支付寶提供的不一樣，支付寶使用的是openssl生成的密鑰，再次百度c# rsa openssl，很好，又一大堆需要學(xué)習(xí)的內(nèi)容，同時也明白了，openssl的密鑰格式是asn.1格式的

最后，因?yàn)槲拿ぷ约菏切枰?net環(huán)境的，所以重點(diǎn)關(guān)注了一下c#相關(guān)的內(nèi)容，找了幾篇文章，終于可以把PKCS8和PKCS1格式的asn密鑰文件成功導(dǎo)入到c#中了

https://www.codeproject.com/Articles/25487/Cryptographic-Interoperability-Keys??Cryptographic Interoperability: Keys

然后，終于明白了PKCS1和PKCS8的密鑰格式。。。。其實(shí)說起來也非常簡單。。。。

先說說PKCS1的私鑰密鑰格式

以上是支付寶生成的一個私鑰證書，掐頭去尾之后，解碼一下base64得到數(shù)組

.......之后和PKCS1的格式就一毛一樣了。。。

額。。。。知道這幾個關(guān)鍵格式，那么自己就可以很方便的雙向轉(zhuǎn)換了。。。。

簡單來說，PKCS1和PKCS8的主要分歧開始在第八個字節(jié)，PKCS1直接進(jìn)入到長度、數(shù)據(jù)的階段了，而PKCS8則開始了一個驗(yàn)證階段，但是驗(yàn)證階段結(jié)束后，后邊的數(shù)據(jù)和PKCS1開始進(jìn)入到長度、數(shù)據(jù)階段的內(nèi)容又一毛一樣。。。。

附：c# 導(dǎo)入PKCS1和PKCS8密鑰

總結(jié)

以上是生活随笔為你收集整理的RSA PKCS1和PKCS8的ASN格式的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
