This module provides a MAC class that is used to store information about how the MAC should be calculated (including the MAC key) and a ValueMAC class that provides (H)MAC checking for PSKC key data. The MAC key is generated specifically for each PSKC file and encrypted with the PSKC encryption key. ) annotationsN)PSKC)EncryptedValuez!^(.*#)?hmac-(?P[a-z0-9-]+)$c$V^8dQhRRRRRR/#) algorithm str | Noneargsbytesreturnz hashlib._HashZformat"-/usr/lib/python3.14/site-packages/pskc/mac.py __annotate__r,s& G GZ G G- Gcs^RIHp^RIHp\P V!V4;'gR4pV'd)\ P!VPR4.VO5!#V!RV,4h \dLi;i)z#Return an instantiated hash object.normalise_algorithmDecryptionErrorZZhashzUnsupported MAC algorithm: %r) pskc.algorithmsrpskc.exceptionsr _hmac_url_reZsearchhashlibnewZgroupZ ValueError)rrrrZmatchs&* r _get_hash_objr,sr3/    3I > D D" EE  ;;u{{62:T: : 9IE FF   s&A11 A?>A?cs(V^8dQhRRRRRRRR/#)rrrkey bytes | Nonevaluerr r r r r rr9s.@@:@L@@5@rcsTa^RIpVPWV3Rl4P4#)z0Generate the MAC value over the specified value.Ncs<\S.VO5!#N)r)rrs*r ZZmac..?smI55r)hmacrZdigest)rrrrsf&& r macr9s% 88 5 77=vx@rc V^8dQhRRRR/#)rrrr intr r r r rrBsjSrcsh^RIHp\\V4P4# Td^#i;i)>Recommended minimal key length in bytes for the set algorithm.r)rrr!rZ digest_size)rr& r mac_key_lengthr$Bs40=+7788 s &11cs]tRt^MtRtRRlt]RRl4t]PRRl4t]RR l4t ] PR R l4t ]R R l4t RRlt RRRllt Rt R#)MACaClass describing the MAC algorithm to use and how to get the key.

None of the arguments are required. By default HMAC-SHA1 will be used as a MAC algorithm. If no key is configured a random key will be generated with the length of the output of the configured hash. This function will automatically be called when the configured encryption algorithm requires a message authentication code. z hmac-sha1N)rrosZurandomr4)r*rrs&&&r setupZ MAC.setupsH H &N~~~(DNxxxzz$";";r9sL*# #zz>?
