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

Unless you have a compelling reason for using an asymmetric cipher like RSA (that is, a real need for a public/private key setup, not "wanting to encrypt only small amounts of data"), use a symmetric cipher.
RSA isn't faster than symmetric ciphers like Blowfish for small amounts of data (in fact, it's quite a bit slower, but you barely notice that since it's so little data), it's just that its slowness because much more apparent with large datasets.

If you're going to keep both keys on the same machine, why the fuck would you use RSA?
