Tutorials for OpenSSL libcrypto

i find all the openssl documentation a bit overwhelming, i've found a great introductory tutorial for using EVP functions and blowfish symmtetrical encryption algorithm, i'll prolly use that if i can't figure out how to use RSA

but my real wish would be to find some nice introduction to RSA encryption, simply because i only need to encrypt small ammounts of data, binary structs, to be stored in dbm files

and i read that rsa is great for small ammounts but for larger ammounts like whole files blowfish was faster, i also like the fact that i only have to keep one key for blowfish but i'd still like to give RSA a shot

tldr: howtos or tutorials on using RSA encryption with openssl crypto libs

so i guess libcrypto should only be used by people who understand cryptography, then what is the point of having a easy to use api for ssl?
So people who understand cryptography could have an easy to use API for SSL? There are more of us than you may think.

and for reasons i don't want to go into i wanted the information encrypted
I think you need to go into them. If the entire database is going to be unencrypted while the program is running, especially if it's also swapping to disk, you might as well not bother with crypto.
If you're sharing a computer and just want your little brother to not look at your stuff, I'd suggest just setting up proper access controls in the OS itself.

If you're primarily doing it to learn about libcrypto and openssl, I'd say you're putting the cart in front of the horse. First start with the basics of cryptography before even thinking about applying it.

one thing i need to read up on is the cipher, because i want a password to be input when the program starts in order to decrypt the files data, i assume this password can generate or unlock the cipher in some way but i'll have to read more about that
Dear god.
