SAML Response Decoder.
Decode any SAML 2.0 Response (base64-deflated or plain base64). View the unpacked XML with the assertion, the issuer, the attribute statements, and the conditions. All processing is client-side.
SAML responses contain authentication assertions. Decoding happens locally; nothing is sent over the network.
Decoded SAML appears here
Paste a base64-encoded SAML 2.0 response. The decoder works locally — nothing is sent.
