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'))
