Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nLocal cryptographic RNG and formats with interoperability review; private-key copy lifecycle.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"rsa-key-generator\",\n  \"category\": \"developer-tools\",\n  \"built\": true,\n  \"requirements\": \"Local cryptographic RNG and formats with interoperability review; private-key copy lifecycle.\",\n  \"implementation\": {\n    \"fields\": [],\n    \"input\": false,\n    \"note\": \"2048-bit RSA-OAEP/SHA-256.

([Markdown](https://happytails.ai/en/developer-tools/hmac-generator.md))\n\n## How to use RSA key generator\n\n1. Enter the values you want to calculate and choose the relevant units or settings.\n2. Review the settings, then choose Run RSA key generator.\n3. Review the result, then use Copy result or a download link when available.\n\n## Working with rsa key generator\n\nFormatting makes existing data or code easier to read. Validation checks whether it follows a syntax or schema. Conversion maps it into another representation. Choosing the right operation helps avoid treating a neatly formatted result as proof that the underlying data is correct.\n\n## Common questions\n\n### Does valid JSON mean the data is correct?\n\nSyntax validation only establishes that the text can be parsed as JSON. A schema can check required fields and types, but neither proves that an email address, price or external record is factually correct.\n\n### Is decoding the same as decrypting or verifying?\n\nNo. Base64 and URL encoding are representations, not encryption. Reading a token payload does not verify its signature. Use the specific validation or verification process required by the system receiving the result.\n\nContinue your workflow: [UUID generator](https://happytails.ai/en/developer-tools/uuid-generator/), [File hash](https://happytails.ai/en/developer-tools/file-hash/), [HMAC generator](https://happytails.ai/en/developer-tools/hmac-generator/).\n"
