Beyond OpenSSH: A Universal SSH Key Format Compatibility Layer

paramiko only supports OpenSSH and PKCS#1 SSH formats, but production environments generate seven different formats—PKCS#8, PuTTY, EC keys, and others—that get rejected outright. Building a detection-and-normalization layer using the cryptography library bridges this gap by re-serializing any format to OpenSSH, eliminating a critical bottleneck in production automation and secure key management across diverse infrastructure sources.
