SSL Certificate Tools: Your Complete Browser-Based Security Suite

In today's digital landscape, SSL/TLS security is more critical than ever. Whether you're a developer setting up HTTPS, a system administrator managing certificates, or a security professional conducting audits, having reliable SSL tools is essential. Today, we're thrilled to introduce ConvertAll.io's comprehensive SSL certificate toolkit - five powerful tools that handle every aspect of SSL certificate management, all while maintaining our commitment to privacy-first processing.

🔐 Meet Your New SSL Toolkit

1. SSL Certificate Generator: Create Certificates with Confidence

Our SSL Certificate Generator empowers you to create professional-grade certificates and Certificate Signing Requests (CSRs) directly in your browser:

Self-Signed Certificates: Perfect for development environments and internal testing

Certificate Signing Requests (CSRs): Generate CSRs for submission to Certificate Authorities

Flexible Configuration: Customize Common Name, Organization details, validity periods, and key sizes

Multiple Key Sizes: Support for 2048, 3072, and 4096-bit RSA keys

Advanced Extensions: Configure key usage, extended key usage, and other X.509 extensions

Quick Start Example

Common Name: dev.mycompany.com
Organization: My Company LLC
Country: US
Key Size: 2048 bits
Validity: 365 days

2. Private Key Converter: Universal Format Support

Converting between different private key formats has never been easier. Our Private Key Converter handles:

PEM Format: Standard Base64-encoded format with headers/footers

PKCS#1: RSA-specific private key format (-----BEGIN RSA PRIVATE KEY-----)

PKCS#8: Algorithm-agnostic format (-----BEGIN PRIVATE KEY-----)

OpenSSH: OpenSSH private key format for SSH authentication

Auto-Detection: Automatically identifies input format

Public Key Extraction: Generates corresponding public keys for any private key

3. Certificate Parser: Decode and Analyze X.509 Certificates

Understanding certificate contents is crucial for security audits and troubleshooting. Our Certificate Parser provides:

Complete Certificate Analysis: Subject, issuer, validity periods, extensions

Security Information: Key algorithms, signature methods, key usage

Validity Checks: Expiration warnings and validity status

Fingerprint Generation: SHA-1 and SHA-256 certificate fingerprints

Extension Details: Subject Alternative Names, Basic Constraints, Key Usage

Human-Readable Format: Complex ASN.1 structures presented clearly

4. Key Pair Generator: Secure Cryptographic Foundation

Generate strong cryptographic key pairs with our Key Pair Generator:#### RSA Keys

2048-bit: Recommended minimum for new applications

3072-bit: Enhanced security for sensitive applications

4096-bit: Maximum security for high-value assets

#### ECDSA Keys (Elliptic Curve)

P-256 (secp256r1): Equivalent to 3072-bit RSA, faster performance

P-384 (secp384r1): Equivalent to 7680-bit RSA, high security

P-521 (secp521r1): Maximum elliptic curve security

5. Certificate Validator: Comprehensive Security Assessment

Our Certificate Validator performs thorough security analysis:

Format Validation: Ensures proper X.509 structure

Validity Period Checks: Expiration and not-before date validation

Key Strength Analysis: Identifies weak keys and algorithms

Extension Compliance: Verifies proper extension usage

Security Best Practices: Checks against current security standards

Trust Chain Analysis: Validates certificate hierarchy

🛡️ Privacy-First Security Processing

Browser-Based Cryptography

All SSL operations leverage the Web Crypto API for secure, native cryptographic operations:

// Example: RSA key generation
const keyPair = await crypto.subtle.generateKey(
  {
    name: "RSA-PSS",
    modulusLength: 2048,
    publicExponent: new Uint8Array([1, 0, 1]),
    hash: "SHA-256",
  },
  true,
  ["sign", "verify"]
);

Zero Server Interaction

No Uploads: Private keys and certificates never leave your browser

💡 Expert Tips for SSL Management

1. Key Size Selection

Use RSA 2048-bit minimum, 4096-bit for high security

Consider ECDSA P-256 for performance-critical applications

Plan for future quantum resistance with larger key sizes

2. Certificate Lifecycle Management

Monitor expiration dates proactively (30-60 days before expiry)

Implement automated renewal processes

Maintain certificate inventory and documentation

3. Security Monitoring

Regularly validate certificate chains

Monitor for weak cipher suites and protocols

Track SSL/TLS vulnerability advisories

4. Development Best Practices

Use different certificates for development, staging, and production

Never use production certificates in development environments

Implement certificate pinning for critical applications
