Build output is byte-identical; SubtleTests.html runs green. --- README.md | 6 +- build.mjs | 94 +++++++++---------- {scripts => src}/aes-cbc.js | 0 {scripts => src}/aes-gcm.js | 0 {scripts =>

Use a null/undefined check so falsy-but-valid results still complete the operation. --- dist/msrcrypto.js | 2 +- dist/msrcrypto.min.js | 2 +- src/subtle/workerManager.js | 9 ++++++--- 3 files changed,

2026 08:38:07 -0700 Subject: [PATCH 42/42] Replace modExp window-size search with calibrated lookup table Compute the fixed-window width for modExp from a precomputed threshold table instead of an iterative cost-minimization loop. The previous model omitted the constant-time getTableEntry scan term and so over-sized the window (selecting 5/6/6 for RSA-1024/2048/4096 signing); the corrected cost model now picks 3/4/5. Thresholds are documented with the model they were derived from and verified against RSA-1024/2048/4096 signing. --- dist/msrcrypto.js | 25 ++++++++++++--------- dist/msrcrypto.min.js | 2 +-
