Web31. I'm assuming you mean a base 64 encoded key file, since removing the newlines from a binary file would obviously break things. The RSA standards (e.g. RFC 2459) only define a binary representation for keys. In practice, like OpenPGP keys ( RFC 4880 ), they are often encoded in base 64 using the otherwise obsolete PEM standards ( RFC 1421 ). WebOne has to do some major fiddling to get OpenSSL to generate an RSA keypair less than 1024 bits. But yes, if the key is small enough it is insecure welcome to the world of cryptography. – ewanm89 Nov 10, 2012 at 15:27 And any certificate authority willing to sign certs with such small keys shouldn't have root certificates in any use. – ewanm89 brian kelly salary history https://mechartofficeworks.com
