# Delphi OpenSSL Library
[Delphi](http://www.embarcadero.com/products/delphi) implementation of [OpenSSL](https://openssl.org/).
## Features
- Encrypt/Decrypt using RSA algorithm
- Symmetric cipher routines (for now only AES256)
- Base*** encoding e decoding
- Basic PAM support
## Usage
### Encrypt with the public key inside X509 certificate
*Command line:*
OpenSSL rsautl -encrypt -certin -inkey publiccert.cer -in test.txt -out test.txt.cry
*Source code:*
```
#!delphi
var
RSAUtil :TRSAUtil;
Cerificate :TX509Cerificate;
begin
RSAUtil := TRSAUtil.Create;
try
Cerificate := TX509Cerificate.Create;
try
Cerificate.LoadFromFile('publiccert.cer');
RSAUtil.PublicKey.LoadFromCertificate(Cerificate);
RSAUtil.PublicEncrypt('test.txt', 'test.txt.cry');
finally
Cerificate.Free;
end;
finally
RSAUtil.Free;
end;
end;
```
### Encrypt with the public key in PEM format
*Command line:*
OpenSSL rsautl -encrypt -pubin -inkey publickey.pem -in test.txt -out test.txt.cry
*Source code:*
```
#!delphi
var
RSAUtil :TRSAUtil;
begin
RSAUtil := TRSAUtil.Create;
try
RSAUtil.PublicKey.LoadFromFile('publickey.pem');
RSAUtil.PublicEncrypt('test.txt', 'test.txt.cry');
finally
RSAUtil.Free;
end;
end;
```
### Decrypt with the private key in PEM format
*Command line:*
OpenSSL rsautl -decrypt -inkey privatekey.pem -in test.txt.cry -out test.txt
*Source code:*
```
#!delphi
var
RSAUtil :TRSAUtil;
begin
RSAUtil := TRSAUtil.Create;
try
RSAUtil.PrivateKey.OnNeedPassphrase := PassphraseReader;
RSAUtil.PrivateKey.LoadFromFile('privatekey.pem');
RSAUtil.PrivateDecrypt('test.txt.cry', 'test.txt');
finally
RSAUtil.Free;
end;
end;
```
## Todo
- Symmetric cryptography (partially done)
- compute hash functions
- Sign e verify
- Generation of pseudo-random bit strings
- RSA data management
- Data managing for X509
- Manage information according to the PKCS #12 standard
## Prerequisite
OpenSSL library must be in your system path
## Installation
- Add the source path "Source" to your Delphi project path
- Run the demo and follow the tutorial
