Implementation of SHA-256, PKCS#1 cryptographie in existing banking software

Hi freelancer, i have an existing german hbci banking software. I need to implement the RDH-10 signature hashing in this existing software. I'll give you a code snippet of my software, a code snippet of another project which has alread done this in Java Code and the german spezifikation. If you can do the job please ping me at Skype: [text hidden] or WhatsApp +[text hidden]. Pleas write me only if you are a developer. It can be done less than 1 hour if you know the spezification. I will give you 50 Euro for one hour. It should be done till today evening. This is the explanation of needed signature code from another project where you can find the code passage. You can find out what HBCI4Java is in the place https://github.com/willuhn/hbci4java/blob/master/src/org/kapott/hbci/security/Sig.java#L359 Line 359. Specifically, the value of the byte array "signature". This is generated in line 337. The "passport" is here an instance of the type AbstractRDHSWPassport. The methods "sign" or "hash" are therefore found in this or the classes from which it is derived. NOTE: YOU WILL GET NO (!!!) FRONTLOAD. I've you have done the maybe 20 lines of code you will get your money!
