Convert RSA key to PKCS8

PKCS #8 is a standard syntax for storing private key information. PKCS #8 is one of the family of standards called Public-Key Cryptography Standards (PKCS) created by RSA Laboratories. The latest version, 1.2, is available as RFC 5208.

The PKCS #8 private key may be encrypted with a passphrase using the PKCS #5 standards, which supports multiple ciphers.

A new version 2 was proposed by S. Turner in 2010 as RFC 5958 and might obsolete RFC 5208 someday in the future.

PKCS #8 private keys are typically exchanged in the PEM base64-encoded format.

Convert RSA key to PKCS1

In cryptography, PKCS #1 is the first of a family of standards called Public-Key Cryptography Standards (PKCS), published by RSA Laboratories.

It provides the basic definitions of and recommendations for implementing the RSA algorithm for public-key cryptography. It defines the mathematical properties of public and private keys, primitive operations for encryption and signatures, secure cryptographic schemes, and related ASN.1 syntax representations.
