Responsibilities: * generate a stable server fingerprint (used for de-dup / re-registration) * persist the backend-assigned server_id into agent.conf * read/write the agent token under a root-only secrets dir SECURITY: install tokens are NEVER written here. Only the long-lived agent token is persisted (v1 returns no refresh token). The token is stored as a plain file with restrictive permissions (0600) inside the root-only secrets directory (0700). The agent has no third-party dependencies, so it installs and runs on a clean Linux server without pip; sealing/encryption is a production TODO that must not reintroduce a runtime dependency. ) annotationsN)Path)Config) get_loggeridentitycT[R"SURS5USS5$)zFDerive 256-bit key from fingerprint and salt using PBKDF2-HMAC-SHA256.sha256utf-8i' )hashlib pbkdf2_hmacencode) fingerprintsalts 2D:\Programs\laragon\www\wolf\agent\src\identity.py _derive_keyr s'   x););G)DdESU VVcN[R"S5n[R"S5n[X5nURS5n[ [ U55nSn[ S[ U5S5HnURSS5n [R"XCU -[R5R5n [S[ U5U- 5n [ U 5Hn XXU -X- XhU -'M US- nM X#-[U5-n SU R53$) zQEncrypt token using standard HMAC-CTR stream cipher bound to machine fingerprint.r rr bigwp_enc:)osurandomrr bytearraylenrangeto_byteshmacnewr r digestminbyteshex)tokenrrivkey plaintext ciphertext block_indexoffset counter_byteskeystream_block chunk_sizeipayloads r encrypt_tokenr2%s ::b>D BB k (C W%I3y>*JK3y>2.#,,Q6 ((3](:GNNKRRTS^f45 z"A%.z%:_=O%OJz "#q /i% ++G W[[]O $$rctURS5(dU$[RUSS5n[U5S:a [ S5eUSSnUSSnUSSn[ X5n[ [U55nSn[S[U5S5Hn URSS 5n [R"XdU -[R5R5n [S[U5U - 5n [U 5Hn XYU -X- XyU -'M US - nM [U5RS 5$) zYDecrypt token using standard HMAC-CTR stream cipher (returns plaintext if not encrypted).rNr z&Invalid encrypted token payload lengthrrrrrr ) startswithr$fromhexr ValueErrorrrrrr r!r r r"r#decode)encrypted_datarr1rr'r*r(r)r+r,r-r.r/r0s r decrypt_tokenr:<s0  $ $Y / /mmN12./G 7|bABB 3B A A A A AAc4[R"5nUS$)z9Best-effort stable MAC-derived value from uuid.getnode().012x)uuidgetnode)nodes r _primary_macrKas <<>D4[rc[S5=(d [S5=(d S[R"5[5/n[R "SR U5RS55R5nSUSS3$) aNBuild a stable, non-secret server fingerprint.
