openssl-pkeyparam - public key algorithm parameter processing command

🚀 Quick Reference

Use Case	Command	Description
🔍 View parameters in text	openssl pkeyparam -in param.pem -text	Prints the parameters in plain text format
✅ Check parameter correctness	openssl pkeyparam -in param.pem -check	Validates the parameter file
🚫 Output without encoded version	openssl pkeyparam -in param.pem -noout -text	Only prints text, no PEM output

📋 SYNOPSIS

openssl pkeyparam [-help] [-in filename] [-out filename] [-text]
[-noout] [-check] [-engine id] [-provider name] [-provider-path path]
[-propquery propq]

📖 DESCRIPTION

This command processes public key algorithm parameters. They can be checked for correctness and their components printed out.

⚙️ OPTIONS

🔹 -help

📖 Print out a usage message.

🔹 -in filename

📂 This specifies the input filename to read parameters from or standard input if this option is not specified.

🔹 -out filename

📦 See "Provider Options" in openssl(1), provider(7), and property(7).

💡 EXAMPLES

openssl pkeyparam -in param.pem -text

📝 NOTES

There are no -inform or -outform options for this command because only PEM format is supported because the key type is determined by the PEM headers.
