ERS Director

ERS Director is an entrypoint ERS that is deployed at https://*.vrfy.ch. It conducts a chip lookup based its public key and derived chipId and will resolve to the desired contentApp in the ERS registry. When redirecting a chip, all query paramaters will included, for example an Arx chip might look like this:

?av=&A02.01.000090.9BFF4326v=01.C5.000005.20F240F4&flags=00&pk1=0428C896E83F6B51C838ADD8C537BD1F2CD45AB152B75436C2BCFBFEAE2905C09D8F03F3071E609CFCE6B3A5E1397484B5EFE2F054C1093F05825999442E8688FE&pk2=040523464ACA95D50C5945A40FF62F36E2227A9123AFBED627ED3E11207B593C24FFC78E17B28039F30E572B90C4496AB42AA12755092270FEBCCA2BA7DF0139FF&latch2=0101010101010101010101010101010101010101010101010101010101010101&rnd=000000507A27899EC02BF491F5B469D48CC45BE4C045E206903E3865BA96D382&rndsig=304502202FB534B05B6B36B5DCB73D180BF3BC001F1EC06D8B9DC7DAC3036C910B2A5BFF022100C89E36BA52647F3AC89175A6D3D7436F550FB02977DF89E4D0DDA27F11FAC66E04&cmd=0101&res=304402201A2093A9440620536C0F929B608D775948397BB6EAB0605A685B8130C7A407AC02202326F45A3F8566B5F1D3D083E80B76C5A1AA0A9036E3772197D92F60994B80B4

If the chipId or associated contentApp cannot be located, then the user will be redirected to the bootloader app for the chip. Typically this is boot.arx.org for Arx HaLo chips.
