- Certificates valid for less than a week
- Certificates valid for less than a month
- Certificates not yet valid
- Property
- With private key
- Is a certificate authority
- Is a request
- Was generated using one of the following key algorithms: RSA, NIST curves, ED448, ED25519
- NIST curve types: secp224r1, secp256r1, secp384r1, secp521r1, secp256k1
- Key size 1024, 1536, 2048, 3072, 4096, 6144 and 8192
- Key usage: Content commitment, CRL signature, data encryption, decryption only, digital signature, encryption only, key agreement, key certificate signature, key encryption
- Extended key usage: Any advanced key usage, client authentication, code signature, e-mail protection, OCSP signature, server authentication, time stamp
- Hash algorithms: sha1, sha224, sha256, sha384, sha512
- Reasons for revocation: Unspecified, key compromised, CA compromised, affiliation changed, replaced, business discontinuation, rights revoked, attribute authority compromised
- Text
- Common Name contains entered text

- Fingerprint contains entered text
- Signature contains entered text
Note: For each suggestion, you can specify whether to use this as an inclusion filter (After selection, the suggested filter is inserted into the input field as a search criterion. The list of certificates is adapted to the search query./ AND) or exclusion filter (
/ AND-NOT).
- Status
Repeat the above steps until you have added the desired filter criteria to your query.
Important: Only entries that match all filter criteria are displayed.
To delete a filter criterion in a search query, click on .
You can add multiple lines to your search by clicking on + OR next to the input field. You can choose to insert a new blank line or to copy the last created line. Each line is a separate search query, which is ORed with the other lines.
