Could someone PM me the addresses of old bridge protocols?

Could someone send me bridge addresses of old bridge protocols like fte, scramblesuit, flashproxy, obfs2, meek-google, etc.,? I’m making an archive of all bridge protocols and I just want a few addresses as examples. Oh, and one more thing: They shouldn’t belong to active or working bridges, only for bridges that once existed but no longer exist.

replying in public because this is all public data, and can be useful to others:

there are probably PTs I forgot, I got at least one of each transport I was able to recall.

from old pt-bundle:
flashproxy: Bridge flashproxy
obfs2: Bridge obfs2 1F01A7BB60F49FC96E0850A6BAD6D076DFEFAF80
obfs3: Bridge obfs3 2ADFE7AA8D272C520D1FBFBF4E413F3A1B26313D

from a ticket
fte: Bridge fte A17A40775FBD2CA1184BF80BFC330A77ECF9D0E9

from an old manpage
scramblesuit: Bridge scramblesuit password=WFVTIHBLAHNBXWSUD6WYTEST42LPIPRT

random example from godoc : Bridge meek url=https://forbidden.example/ front=allowed.example
google: Bridge meek url=
amazon: Bridge meek url=
azure: Bridge meek url=

amazon: Bridge meek_lite B9E7141C594AF25699E0079C1F0146F409495296 url= ff
azure: Bridge meek_lite 97700DFE9F483596DDA6264C4D7DF7641E1E39CE url=

these are currently valid bridges, but they aren’t secret (they are default bridges)
obfs4: Bridge obfs4 D9A82D2F9C2F65A18407B1D2B764F130847F8B5D cert=bjRaMrr1BRiAW8IE9U5z27fQaYgOhX1UCmOpg2pFpoMvo6ZgQMzLsaTzzQNTlm7hNcb+Sg iat-mode=0
meek: Bridge meek_lite BE776A53492E1E044A26F17306E1BC46A55A1625 url=
snowflake: Bridge snowflake 2B280B23E1107BB62ABFC40DDCC8824814F80A72 fingerprint=2B280B23E1107BB62ABFC40DDCC8824814F80A72 url=,,,,,,,, utls-imitate=hellorandomizedalpn

upcomming transports:
webtunnel: Bridge webtunnel url=
conjure: Bridge conjure url=


Can I send the list here? Just for archival purposes so that the next generation will know how the bridge addresses that used to be used for older bridges.

There’s a detailed timeline of when default bridges were added in the first half of 2016 and how long it took censors to block them: Time delays in censors’ reactions.

See also Censors’ Delay in Blocking Circumvention Proxies and from the same experiment.

Until 2017, the default bridges were stored in the file Bundle-Data/PTConfigs/bridge_prefs.js in the tor-browser-bundle repository. You can see the history of that file to track changes. Between 2017 and 2022 the list was in projects/tor-browser/Bundle-Data/PTConfigs/bridge_prefs.js in the tor-browser-build repository (history). After #40436, the list moved from bridge_prefs.js to multiple files under /projects/common.

You can also find some information at the Metrics Timeline by searching for “default bridge”.
