RSA - Weak Keys

Intro Did you ever try to generate a small RSA Key ? Today, you should go with 3072 oder 4096 Bits, or use ECC. With current Versions of OpenSSL, you can’t generate Key Smaller than 512 Bit. 128 Bit Key import rsa pubkey,privkey = rsa.newkeys(128) print(pubkey.save_pkcs1('PEM').decode('UTF-8')) print(privkey.save_pkcs1('PEM').decode('UTF-8')) 32 Bit Key import rsa pubkey,privkey = rsa.newkeys(32) print(pubkey.save_pkcs1('PEM').decode('UTF-8')) print(privkey.save_pkcs1('PEM').decode('UTF-8')) 16 Bit Key import rsa pubkey,privkey = rsa.newkeys(16) print(pubkey.save_pkcs1('PEM').decode('UTF-8')) print(privkey.save_pkcs1('PEM').decode('UTF-8')) sample with 16Bit RSA Key
