The RSA encryption algorithm is an asymmetric encryption algorithm. RSA is widely used in public key encryption and electronic commerce. The RSA was proposed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. The RSA is composed of the letters of the three names of the three of them. The reliability of the RSA algorithm ...

WebUnrelated but analogous, OpenSSL has many crypto primitives same as SSH and uses nominal PEM for many things; it writes 64 chars (per 1421), reads 76 chars (per 2405) in most cases and silently drops anything longer, although there has recently been discussion on the dev list about fixing this. – dave_thompson_085 Sep 10, 2014 at 6:53
