iOS RSA加密解密及簽名驗證，iosrsa

1.首先要下載openssl,這個不用說,直接官網下載或者用brew install openssl下載

2.終端產生私密金鑰密鑰

2.1產生私密金鑰

openssl genrsa -out rsa_private_key.pem 1024

2.2產生密鑰

openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

2.3將RSA私密金鑰轉換為pkcs8 格式

openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt -out rsa_private_key.pem

私密金鑰及密鑰地址在根目錄檔案 rsa_private_key.pem  rsa_public_key.pem

問價可通過右鍵檔案編輯器開啟查看

也可以通過終端命令cat rsa_private_key.pem 及 cat rsa_pubilic_key.pem 查看私密金鑰密鑰字串

3.匯入openssl ,匯入HBRSAHandler 檔案夾

小技巧：拖進去後：librarySearchpath：會自動化佈建，然後拷貝路徑到headSearchpath，後邊添加/include。

4.使用:

兩種方式匯入密鑰然後調用響相應的方法即可。

4 結果驗證（註：公開金鑰加密，每次加密的結果會不一樣，但是私密金鑰簽名的結果每次都一樣）
