Re: decrypt base65 file with openssl

[Mohamad Badra]

Hello again, In fact, I tried the base64 command (base64 -e input file) on the hexadecimal file. a)Firstly, the file's length increases from 256 to 349 bytes. Is it normal? b)Secondly, the base64 takes the hexa and give me base64 format. What I need is the exact format (I think it is the pkcs1 format but i don't know how I can have it) of the encrypted file to decrypt it using RSA key. To summarize, I have an encrypted file in hexadecimal format, and I have to decrypt it using RSA algorithm. Thank you in advance. -Bdr Dr. Stephen Henson wrote: On Mon, Dec 15, 2003, Mohamad Badra wrote: Dear, I have a trace of SSL client/server session and the server's RSA private key. During the SSL session, the client encrypts a 48 bytes premastersecret with the server public key. I have the encrypted premastersecret coding in Base64. Must i translate it to any specific format before decrypt it using the server's private key? Just base64 decode it to binary. Steve. -- Dr Stephen N. Henson.
