Ed25519Error

Cryptographic random seed generation failed.

Thrown when the system’s secure random number generator fails to produce the required entropy for seed generation. This is a critical error that should be rare in normal circumstances.

The provided seed string (S-address) is invalid or malformed.

This occurs when:

• The seed string doesn’t start with ‘S’
• The base32 decoding fails
• The checksum validation fails

The seed byte array has an incorrect length.

Seeds must be exactly 32 bytes. This error is thrown when attempting to create a Seed from a byte array of any other length.

The scalar value has an incorrect length.

Ed25519 scalars must be exactly 32 bytes.

The provided public key string (G-address) is invalid or malformed.

This occurs when:

• The account ID doesn’t start with ‘G’
• The base32 decoding fails
• The checksum validation fails

The public key byte array has an incorrect length.

Public keys must be exactly 32 bytes. This error is thrown when attempting to create a PublicKey from a byte array of any other length.

The provided private key is invalid.

This indicates that the private key material is malformed or unusable.

The private key byte array has an incorrect length.

Private keys must be exactly 64 bytes (32 bytes secret scalar + 32 bytes public key). This error is thrown when attempting to create a PrivateKey from a byte array of any other length.

The signature byte array has an incorrect length.

Ed25519 signatures must be exactly 64 bytes. This error is thrown when attempting to verify a signature that doesn’t match the expected length.

The keypair does not contain a private key and cannot sign.

Thrown when attempting to sign a message with a public-key-only keypair. Create the keypair from a secret seed or generate a new keypair to sign.
