abylon SELFCERT is a Windows utility for creating self-signed X.509 v3 certificates for private use and testing. It is suited to users who need a certificate ...

BerEditor opens BER-encoded files and presents their contents as a navigable structure, with a tree view, hexadecimal bytes, readable text and details for the selected element. It is designed for examining data found in certificates, smart cards and network protocols. Additional tools support encryption and decryption, digital signatures, one-time passwords, large-number operations and OID lookup.

BerEditor is a BER file viewer and analysis tool for developers, security professionals and others who need to examine encoded data used in certificates, smart cards and network protocols. BER data is stored in binary form, so it is difficult to interpret in a plain text editor. BerEditor presents the file as an organized structure, making its elements easier to navigate and inspect when diagnosing a certificate or investigating data exchanged by a security-related system.
The main view combines a tree of the file's structure with a hexadecimal display and a readable-text view. Selecting an item in the tree lets the user focus on a specific part of the encoding, while the adjacent views show the corresponding raw bytes and any readable characters. A details area explains the selected element, including its type, size and value. This arrangement helps connect the structured representation to the underlying data, which can be useful for checking how fields are encoded or locating unexpected or missing content.
Alongside file inspection, BerEditor includes tools for common cryptography and PKI tasks. It can encrypt and decrypt data, create and verify digital signatures, and generate one-time passwords. Additional utilities handle large numbers used in encryption and provide OID lookup, helping users identify object identifiers found in certificate and security data. Keeping these functions together with the BER viewer can make it easier to move between examining an encoded file and checking related cryptographic information.
Typical uses include inspecting certificate files, investigating why a certificate is rejected, and checking whether a BER-encoded structure appears damaged or lacks expected information. Developers working with smart cards or network protocols can also use the tree and byte views to understand how data is arranged. BerEditor presents the contents for analysis; the user still needs to interpret the results in the context of the relevant certificate, protocol or application.
BerEditor is trialware for 64-bit Windows 10 and Windows 11. Its focused interface is intended for technical work with binary encodings and security data rather than general document editing. The included cryptography utilities make it useful as a compact reference and testing tool, while the BER tree, hexadecimal bytes, readable text and element details provide the core workflow for examining files.
