Results for “hash-cracking”

Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.

Write effective fuzzing harnesses across languages to improve code coverage and find bugs in your system under test.

Filters top Hacker News stories by interest tags and extracts high-signal comments (top, dissenting, expert/builder) with themed clustering.

Compute the SHA-256 hash of a string or file

Build an append-only log integrity chain using SHA-256 hash chaining for tamper detection. Each log entry is hashed with the previous entry's hash to create a blockchain-like structure where modifying any entry invalidates all subsequent hashes.

Heap exploitation playbook. Use when targeting ptmalloc2/glibc heap vulnerabilities including UAF, double free, overflow, off-by-one/null, and leveraging tcache/fastbin/unsortedbin attacks for arbitrary write or code execution.

Prevents Ethereum hashing bugs in JavaScript and TypeScript by distinguishing Keccak-256 from Node's NIST SHA3-256, with usage examples for ethers, viem, and web3.js.

Use HasData APIs for web scraping and structured web data extraction.

Use HasData APIs for web scraping and structured web data extraction.

防止 JavaScript 和 TypeScript 中的以太坊哈希错误。Node 的 sha3-256 是 NIST SHA3，而非以太坊 Keccak-256，会静默破坏选择器、签名、存储槽和地址推导。

Hunt for Pass-the-Hash attacks by analyzing NTLM authentication patterns, identifying Type 3 logons where Kerberos is expected, and correlating with credential dumping indicators.

Detect and exploit HTTP request smuggling vulnerabilities caused by Content-Length and Transfer-Encoding parsing discrepancies between front-end and back-end servers.

Prevents Ethereum hashing bugs by distinguishing Keccak-256 from Node's NIST SHA3-256, with code examples for ethers, viem, and web3.js.

Comprehensive cryptography guidance covering encryption algorithms, password hashing, TLS configuration, key management, and post-quantum considerations. Use when implementing encryption, choosing hashing algorithms, configuring TLS/SSL, managing cryptographic keys, or reviewing cryptographic implementations.

Imported skill tracing from langchain

Extract public web data, search engine results, and structured data from platforms like Google, Amazon, and Zillow using HasData APIs.

Hunt for web shell deployments on internet-facing servers by analyzing file creation in web directories, suspicious process spawning from web servers, and anomalous HTTP patterns.

Compress, extract, list, and encrypt ZIP archives in batch. Use when archiving files, extracting packages, listing contents, encrypting backups, or batching.

Scrapes Danish job sites for new positions matching your profile. Deduplicates across runs. Triggers on: job scrape, find jobs, search jobs, new jobs, job search, scrape jobs, /scrape

Detect data staging activity before exfiltration by monitoring for archive creation with 7-Zip/RAR, unusual temp folder access, large file consolidation, and staging directory patterns via EDR and process telemetry.

Use HasData APIs for web scraping and structured web data extraction.

Use HasData APIs for web scraping and structured web data extraction.

Provides guidance for using python-xxhash to implement fast non-cryptographic hashing, including algorithm selection, byte encoding, streaming updates, digest representation, and collision-aware identity for checksums, bucketing, and sampling.

Use HasData APIs for web scraping and structured web data extraction.

Explains cryptographic primitives and provides Python implementations for encryption, hashing, key exchange, and digital signatures.

Compress, extract, list, and encrypt ZIP archives in batch. Use when archiving files, extracting packages, listing contents, encrypting backups, or batching.

Detects DNS tunneling by computing Shannon entropy of DNS query names, analyzing query length distributions, inspecting TXT record payloads, and identifying high subdomain cardinality using scapy for packet capture analysis.
