(If compiled with KMS support, length will vary; see [Optional Features](#optional-features))\n\n`batch_size` | `ROUGHENOUGH_BATCH_SIZE` | Optional | The maximum number of requests to process in one batch. All nonces in a batch are used to build a Merkle tree, the root of which is signed. Default is `64` requests per batch.\n\n`status_interval` | `ROUGHENOUGH_STATUS_INTERVAL` | Optional | Number of _seconds_ between each logged status update. Default is `600` seconds (10 minutes).\n\n`health_check_port` | `ROUGHENOUGH_HEALTH_CHECK_PORT` | Optional | If present, enable an HTTP health check responder on the provided port. **Use with caution**, see [Optional Features](#optional-features).\n\n`kms_protection` | `ROUGHENOUGH_KMS_PROTECTION` | Optional | If compiled with KMS support, the ID of the KMS key used to protect the long-term identity. See [Optional Features](#optional-features).\n\n`fault_percentage` | `ROUGHENOUGH_FAULT_PERCENTAGE` | Optional | Likelihood (as a percentage) that the server will intentionally return an invalid client response. An integer range from `0` (disabled, all responses valid) to `50` (50% of responses will be invalid). Default is `0` (disabled).\n\n\n","file_path":"README.md","rank":35,"score":20754.27537364356},{"content":"# Or using environment variables\n\n$ export ROUGHENOUGH_INTERFACE=127.0.0.1\n\n$ export ROUGHENOUGH_PORT=8686\n\n$ export ROUGHENOUGH_SEED=f61075c988feb9cb700a4a6a3291bfbc9cab11b9c9eca8c802468eb38a43d7d3\n\n$ target/release/roughenough-server ENV\n\n2018-07-25 00:05:09 INFO [server] Roughenough server v1.0.5 starting\n\n2018-07-25 00:05:09 INFO [server] Long-term public key: d0756ee69ff5fe96cbcf9273208fec53124b1dd3a24d3910e07c7c54e2473012\n\n2018-07-25 00:05:09 INFO [server] Ephemeral public key: 25fd5dc31ceee241aed3e643534e95ed0609e9a20982a45ac0312a5f55e2cc66\n\n2018-07-25 00:05:09 INFO [server] Server listening on 127.0.0.1:8686\n\n```\n\n\n\nThe resulting binary is `target/release/roughenough-server`.

The motivation for this change is unclear and it complicates implementations\n\nwhich now need two hashing primitives (SHA-512/256 initialization is different than SHA-512).\n\n\n\nSuggestion: use SHA-512 throughout and drop any use of SHA-512/256\n\n\n\n## References \n\n\n\n* [AWS-smear] https://aws.amazon.com/blogs/aws/look-before-you-leap-the-coming-leap-second-and-aws/\n\n* [CF-DDoS] https://www.cloudflare.com/learning/ddos/ntp-amplification-ddos-attack/\n\n* [CWE-190] https://cwe.mitre.org/data/definitions/190.html\n\n* [CWE-TOP25] https://cwe.mitre.org/top25/archive/2019/2019_cwe_top25.html\n\n* [draft02] https://tools.ietf.org/html/draft-ietf-ntp-roughtime-02\n\n* [Google-smear] https://developers.google.com/time/smear\n\n* [int08h] https://int08h.com/post/to-catch-a-lying-timeserver/#keeping-response-sizes-compact\n\n* [roughtime] https://roughtime.googlesource.com/roughtime\n\n\n","file_path":"doc/rfc-commentary.md","rank":50,"score":19345.17244966042},{"content":"# Comments on draft-ietf-ntp-roughtime-02\n\n\n\nAuthor: Stuart Stock\n\nDate : 2020-06-14\n\n\n\n## Introduction\n\n\n\nI am the original creator and current maintainer of two Roughtime implementations:\n\n\n\n * Roughenough (Rust) https://github.com/int08h/roughenough\n\n * Nearenough (Java) https://github.com/int08h/nearenough\n\n\n\nHave written deep-dive articles about the Roughtime protocol: \n\n\n\n * https://int08h.com/post/to-catch-a-lying-timeserver/\n\n * https://int08h.com/post/roughtime-message-anatomy/\n\n \n\nAnd operate the longest running publicly accessible (non-Googler) Roughtime server \n\non the internet\n\n\n\n * roughtime.int08h.com:2002\n\n \n\nI offer my comments on draft-ietf-ntp-roughtime-02 as someone well versed in the Roughtime \n\nprotocol and intimately familiar with its implementation and trade-offs.\n\n\n\n## Keep the \"rough\" in \"Roughtime\"\n\n\n\nThe authors of the original Roughtime protocol definition [roughtime] state that a \n\ndeliberate goal of the Roughtime protocol was \"...time synchronisation to within 10 \n\nseconds of the correct time.\" Those authors go on to state that \"[i]f you have \n\n_serious_ time synchronisation needs you‘ll want the machinery in NTP or even PTP...\"\n\n\n\nAddition of the DUT, DTAI, and LEAP fields run contrary to this design intent.

(If compiled with KMS support, length will vary; see [Optional Features](#optional-features))\\n\\n`batch_size` | `ROUGHENOUGH_BATCH_SIZE` | Optional | The maximum number of requests to process in one batch. All nonces in a batch are used to build a Merkle tree, the root of which is signed. Default is `64` requests per batch.\\n\\n`status_interval` | `ROUGHENOUGH_STATUS_INTERVAL` | Optional | Number of _seconds_ between each logged status update. Default is `600` seconds (10 minutes).\\n\\n`health_check_port` | `ROUGHENOUGH_HEALTH_CHECK_PORT` | Optional | If present, enable an HTTP health check responder on the provided port. **Use with caution**, see [Optional Features](#optional-features).\\n\\n`kms_protection` | `ROUGHENOUGH_KMS_PROTECTION` | Optional | If compiled with KMS support, the ID of the KMS key used to protect the long-term identity. See [Optional Features](#optional-features).\\n\\n`fault_percentage` | `ROUGHENOUGH_FAULT_PERCENTAGE` | Optional | Likelihood (as a percentage) that the server will intentionally return an invalid client response. An integer range from `0` (disabled, all responses valid) to `50` (50% of responses will be invalid). Default is `0` (disabled).\\n\\n\\n\",\n \"file_path\": \"README.md\",\n \"rank\": 35,\n \"score\": 20754.27537364356\n },\n {\n \"content\": \"# Or using environment variables\\n\\n$ export ROUGHENOUGH_INTERFACE=127.0.0.1\\n\\n$ export ROUGHENOUGH_PORT=8686\\n\\n$ export ROUGHENOUGH_SEED=f61075c988feb9cb700a4a6a3291bfbc9cab11b9c9eca8c802468eb38a43d7d3\\n\\n$ target/release/roughenough-server ENV\\n\\n2018-07-25 00:05:09 INFO [server] Roughenough server v1.0.5 starting\\n\\n2018-07-25 00:05:09 INFO [server] Long-term public key: d0756ee69ff5fe96cbcf9273208fec53124b1dd3a24d3910e07c7c54e2473012\\n\\n2018-07-25 00:05:09 INFO [server] Ephemeral public key: 25fd5dc31ceee241aed3e643534e95ed0609e9a20982a45ac0312a5f55e2cc66\\n\\n2018-07-25 00:05:09 INFO [server] Server listening on 127.0.0.1:8686\\n\\n```\\n\\n\\n\\nThe resulting binary is `target/release/roughenough-server`.

Upgrade to at least v2.0.0 to build without any of these flags.\n\n\n\n## Backend\n\n\n\nThe backend (in Rust) gets daily snapshots of your wallets and the price history for each cryptocurrency you have in your wallets.\n\n\n\nUsed APIs:\n\n\n\n- Binance API for the wallets snapshots (with the [Daily Account Snapshot](https://binance-docs.github.io/apidocs/spot/en/#daily-account-snapshot-user_data) endpoint)\n\n- Nomics API for the price history (with the [Currencies Sparkline](https://nomics.com/docs/#operation/getCurrenciesSparkline) endpoint)\n\n\n\nThe Binance API **does not give the fiat amount** corresponding to each cryptocurrency you have, hence the need of the Nomics API to get the price history.\n\n\n\nA MongoDB database is used to store this data as NoSQL. So when we ask for data in a time range, only the missing data is requested to APIs. The database contains **daily** data points and it is normalized to be at midnight (00:00) for each day.\n\n\n\n- Binance API saves snapshots each day at 23:59 (stored in MongoDB as +1 minute, which is the next day)\n\n- Nomics API gives a price history with data points at 00:00 (stored in MongoDB as is)\n\n\n","file_path":"README.md","rank":51,"score":2.6615320672727893}],"string":"[\n {\n

So when we ask for data in a time range, only the missing data is requested to APIs. The database contains **daily** data points and it is normalized to be at midnight (00:00) for each day.\\n\\n\\n\\n- Binance API saves snapshots each day at 23:59 (stored in MongoDB as +1 minute,
