Web5 sep. 2014 · RSA is used to encrypt messages that are shorter than the modulus of the public key. For 1024-bit keys, this means that the message must be 117 bytes or fewer (the modulus is 128-bytes, minus 11 for the padding of the message). Attempting to encrypt a message that is larger than the modulus will result in the error: System error: Message … Web11 jun. 2024 · RS256 message too long for RSA public key size · Issue #408 · dgrijalva/jwt-go · GitHub This repository has been archived by the owner on May 21, …
