Gen RSA key

telegram客户端使用的是pkcs1格式公钥证书

参考

rsa秘钥介绍及openssl生成命令

Genkey

    openssl genrsa -out server.key 2048

    convert pcks8:
    openssl pkcs8 -topk8 -inform PEM -in server.key -outform pem -nocrypt -out server8.key
    openssl rsa -in server.key -pubout > public_pkcs8.pub

    convert pcks1:
    openssl rsa -in server.key -outform PEM -RSAPublicKey_out -out public_pkcs1.key

gen fingerprint

fingerprint.go

./fingerprint test.key
