OV SSL Certificate Price: What It Costs in 2026
OV SSL runs about $30–$300 a year in 2026, with My-SSL's from $29 and an OV wildcard from $89. What the premium over DV actually buys, how OV compares to DV and EV, the four levers that move the price, and why the 199-day cap changes your calendar but not your invoice.
What Is an SSL Certificate Warranty? What It Really Covers
An SSL certificate warranty reimburses the relying party — your customer, not you — if the CA mis-issues your certificate. What it actually covers, why hacks and breaches never qualify, the warranty amounts behind DV, OV, and EV, and whether the figure should sway your purchase.
Wildcard SSL Certificate Price: What It Costs in 2026
DV wildcard SSL runs about $50–$225 a year and OV about $100–$420 in 2026. What actually drives the price, why EV wildcards don't exist at any price, when a wildcard beats separate certificates, and how the 199-day validity cap changes renewals (without changing the sticker).
How to Sign a Windows EXE on Linux or macOS (osslsigncode)
Sign Windows EXE, MSI, and DLL files from Linux or macOS with osslsigncode: install it, connect your hardware token or SimplySign cloud key over PKCS#11, hash with SHA-256, and add an RFC 3161 timestamp. The signature is identical to signtool's — the private key just has to stay on certified hardware.
How to Sign a NuGet Package (Step by Step)
Sign a NuGet package with dotnet nuget sign: use a hardware-based code signing certificate, reference it by SHA-256 fingerprint, add an RFC 3161 timestamp, then register the certificate on NuGet.org and verify. Includes the author-vs-repository signature split and the errors most first uploads hit.
How to Sign a VBA Macro (Word, Excel & PowerPoint)
Sign a VBA macro in Word, Excel, or PowerPoint: choose a code signing certificate in the VBA editor, timestamp it through the registry, and set your publisher as trusted. Plus why a correctly signed macro can still hit the red 'Microsoft has blocked macros' banner — and the fix.
How to Install an S/MIME Certificate in Outlook (Windows, Mac & Web)
Get your S/MIME certificate working in every Outlook: import the .pfx into the store each version actually reads — Windows store, Outlook's own S/MIME settings, or the macOS Keychain — pick it as your signing certificate, and trade one signed email before you encrypt. Includes the five errors that stop most first setups.
What Is a Document Signing Certificate? Digital PDF Signatures Explained
A document signing certificate ties a CA-verified identity to your PDF and Office signatures. What separates it from a typed e-signature, how the cryptography works, what Adobe AATL membership changes for recipients, and how the eIDAS levels decide legal weight.
How to Sign a Windows Driver (Attestation Signing, Step by Step)
Kernel drivers only load when Microsoft signs them: what your EV certificate actually signs, the attestation submission in Partner Center step by step, why Windows Server needs WHQL instead, and what the April 2026 cross-signing cutoff broke.
How to Sign an MSI or MSIX Installer (Step by Step)
Sign MSI and MSIX installers with SignTool: why packages sign from the inside out, the one-signature-per-MSI rule that breaks dual signing, the MSIX publisher-match check behind error 0x8007000B, and how Inno Setup, NSIS, and WiX bundles each get signed.
How to Sign a JAR with jarsigner (Step by Step)
Sign a JAR with jarsigner: find your alias with keytool, sign from a keystore file or a PKCS#11 hardware token, timestamp with -tsa, verify with -verify -certs -strict, and decode the warnings — including why modern JDKs treat SHA-1-signed JARs as unsigned.
How to Sign a PowerShell Script (Step by Step)
Sign a PowerShell script with Set-AuthenticodeSignature: pick the right certificate, force SHA256 (Windows PowerShell 5.1 still defaults to SHA-1), add a timestamp, verify with Get-AuthenticodeSignature, and fix HashMismatch, UnknownError, and the untrusted-publisher prompt.
