I am trying to sign a token object using SHA1.
I am using bouncycastle as the security provider.
Whenever the program tries to sign something it gives me this error.
java.security.SignatureException: java.lang.IllegalArgumentException: input data too large.
What is the maximum size for signing something?
Do you have any suggestions about how I can sign this object?
The input size is limited to the size of the key. If you use a 1024 bit key, you are limited to 128 bytes.
Typically, you are signing the digest (hash value), not the actual data.
