when I configure IDP, I tried disable signature and encryption for testing purpose. I enabled SLO as http redirect, when I hit the saml2slo url from browser, I see following in the log:
/affwebservices/public/saml2slo?SAMLRequest=jZJRb5swFIXf%2ByuQ34mxQ0JqAVI0tI41bdpm6sNeImMunTewGde0yb%2BfYdqqTto0yU%2FH5xx%2Fvna6s092dA%2FwfQR0wa11e7Mfto2DISM8YnEYrcIo%2BcQSsUzEin0mQeGN2kinrcnIF%2Bd6FJRiF8qmCXsHi9H4nUqabwtlO%2BrVF6gQhmetAGk%2FVq1WFGXXcmwtCcoiI0cWq81aXW54taxq1dQ1gKwv4xUwnmx4DOulbLwVcYTSoJPG%2FQnH%2FZrgHmHAGYwvIhKcutZgRsbBCCtRozCyAxROicP2Zie8R%2FSDdVbZluSpQSbmM4afQeGFf4cl%2BotNgyD59a68Ph5u7o5lcZfS16qplotbHy2L4L0dOun%2B3skWbFZ0HTazVYwGe1C60VCT31T8v6meZavr%2BanYBPULJE8PgNOcSlPDKX%2Fcr0%2F9%2BePVu2Wx%2BnA%2FXp1p9PI1SqL4qczc9ky7%2ByxL6ZtISt98nPzi4gc%3D&RelayState=1ff0da0b4efca70f2bb78a1f58a5089a5a50b57f HTTP/1.1" 302
Since I already disabled signature and encryption, and I tried use base64 to decode this SAMLRequest, but not valid. Please help me understand what this string format is, is it sign/encrypted with any cert/key...?
