ber_str2bv - Linux
Overview
ber_str2bv is a command-line utility designed to convert a BER-encoded string to its Base64 Variant (BV) representation. It finds application in security and communication protocols like TLS, where BV encoding is commonly used to encode strings securely.
Syntax
ber_str2bv [options] <BER-encoded string>
Options/Flags
- -h, –help: Displays usage information.
- -b, –binary: Output in binary format instead of base64.
- -q, –quiet: Suppress all warnings and errors.
- -v, –verbose: Print detailed messages about the conversion process.
Examples
Convert a BER-encoded string to BV:
ber_str2bv "Hello, world!"
Output in binary format:
ber_str2bv -b "Hello, world!"
Common Issues
- Invalid input: If the provided string is not a valid BER-encoded string, the command will exit with an error.
- Non-printable characters: Output in binary format may contain non-printable characters that can disrupt scripts or commands.
Integration
Use with OpenSSL:
openssl rsa -in private.key -out public.key -pubout | ber_str2bv
