# 443 ) HTTPS

## 01. Heartbleed

```bash
sslyze --heartbleed 10.10.10.79
```

## 02. Sniff Traffic

```bash
sudo mitmdump -p 443 --mode reverse:https://<SERVER-IP> --ssl-insecure --flow-detail=3          
```

## 03. SSL ERRORS

`SSL_ERROR_UNKNOWN_CA_ALERT` / `SSL_ERROR_HANDSHAKE_FAILURE_ALERT`

Need to create CA certificate.

```bash
## ------------------| Grab certificate
openssl s_client -connect IP:443

## ------------------| Verify/Check certificate
## Extension also can be pem,csr
openssl x509 -in PublicKey.cert -text

## ------------------| Create CA certificate
### Generate our key
openssl genrsa -out certificate.key 2048
### Generate certificate signing request 
### Place something for Internet Widgits and FQDN:h4rithd@fourtune.htb      
openssl req -new -key certificate.key -out certificate.csr
### Certificate signing
openssl x509 -req -in certificate.csr -CA PublicKey.cert -CAkey PrivateKey.pem -CAcreateserial -out certificate.pem -days 1024 -sha256             
### Package pkcs12 format for browsers
openssl pkcs12 -export -out certificate.pfx -inkey certificate.key -in certificate.pem -certfile PublicKey.cert
```

## 04. Extract .crt & .key files from .pfx

```bash
openssl pkcs12 -in [yourfile.pfx] -nodes -nocerts -out [drlive.key]
openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [drlive.crt]
openssl rsa -in [drlive.key] -out [drlive-decrypted.key]

openssl rsa -in [keyfile-encrypted.key] -outform PEM -out [keyfile-encrypted-pem.key]
```
