```
public class BlocklistEntries
extends Object
```
Data structure and management for I2P router blocklist entries.
Represents a signed blocklist containing router identifiers to be blocked or unblocked, with support for cryptographic signature verification and timestamp validation.
Provides methods for loading, verifying, and managing blocklist entries with security checks to prevent expired or invalid blocklists. Includes command-line tool for creating signed blocklist files from input text.
All String fields may be null to accommodate optional metadata elements in blocklist feeds.

```
public static void main(String[] args)
```
    BlocklistEntries [-p keystorepw] input.txt keystore.ks you@mail.i2p File format: One entry per line, # starts a comment, ! starts an unblock entry. Single IPv4 or IPv6 address only (no mask allowed), or 44-char base 64 router hash. See MAX_ENTRIES above.
    Parameters:
    args - command line arguments
