Let me show you how to load a Private Key stored in the PEM PKCS#8 file in Java. We will read the file, parse it, remove not needed header and footer and create a new java.security.PrivateKey object that can be later used in our App for cryptography needs.
PEM PKCS#8 is a format for storing private keys in a text file. It is specified in the PublicKey Cryptography Standards (PKCS) #8, which defines a standard syntax for storing private key information. PEM stands for Privacy Enhanced Mail, and refers to a specific Base64 encoded format that is commonly used to store cryptographic keys in ASCII format. The PEM PKCS#8 format is widely used for storing and exchanging private keys, especially in SSL/TLS certificates and encrypted files.
