What is PKCS 7 padding?
PKCS #7 (Cryptographic Message Syntax) is a standard padding method that determines the number of padding bytes and then ads that as a value. For example, for a 128-bit block size, and if we have “testing”, then there are seven bytes (for ASCII coding) that represent the data, and we then have 9 (0x09) padding values.
How do I know if my certificate has a private key?
