Examples

Generate an RSA private key

openssl genrsa -out private.pem 2048

Generate a self-signed certificate

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

Compute SHA-256 hash of a file

openssl dgst -sha256 file.txt

Encrypt a file with AES-256

openssl enc -aes-256-cbc -salt -in plain.txt -out encrypted.enc

Connect to an HTTPS server and inspect certificate

openssl s_client -connect example.com:443 -showcerts

View certificate details

openssl x509 -in cert.pem -text -noout

Documentation

OpenSSL — Cryptographic Toolkit

OpenSSL is the industry-standard cryptographic library that provides tools for SSL/TLS, certificate management, encryption, and hashing. It's essential for secure communications and data protection.

Certificate Management

Generate Certificate Authority

# Generate CA private key
openssl genrsa -out ca-key.pem 4096

# Generate CA certificate
openssl req -x509 -new -key ca-key.pem -out ca-cert.pem -days 3650

Generate Server Certificate

# Generate server private key
openssl genrsa -out server-key.pem 2048

# Generate CSR
openssl req -new -key server-key.pem -out server.csr

# Sign with CA
openssl x509 -req -in server.csr -CA ca-cert.pem -CAkey ca-key.pem -CAcreateserial -out server-cert.pem -days 365

Encryption & Decryption

# Encrypt a file with password
openssl enc -aes-256-cbc -salt -in secret.txt -out secret.enc -pbkdf2

# Decrypt
openssl enc -d -aes-256-cbc -in secret.enc -out secret.txt -pbkdf2

# Encrypt with key file
openssl rsautl -encrypt -pubin -inkey public.pem -in plain.txt -out encrypted.bin

TLS Connection Testing

# Test HTTPS connection
openssl s_client -connect example.com:443 -servername example.com

# Show certificate chain
openssl s_client -connect example.com:443 -showcerts </dev/null

# Test TLS version support
openssl s_client -tls1_2 -connect example.com:443

Hashing

# Compute hash of a file
openssl dgst -sha256 file.txt
openssl sha256 file.txt

# HMAC
echo -n "data" | openssl dgst -sha256 -hmac "key"
