A checksum is a value that represents the number of bits in a transmission message. We want to check the checksum to detect high-level errors within data transmissions. For Vault, the most prevalent use for checksum is for installing Vault auth, secrets, or a custom plugin, here are a few methods to find the checksum value:
1. shasum (Terminal/Linux)
shasum -a 256 /Users/test_user/vault_pki/vault_plugins/venafi-pki-backend 6bb213b74abc5a2c5683b0d48022cc30ba77e55db7cc47f59ba99886737605c8
2. openssl sha256 (Terminal/Linux)
penssl sha256 /Users/test_user/vault_pki/vault_plugins/venafi-pki-backend
SHA256(/Users/test_user/vault_pki/vault_plugins/venafi-pki-backend)= 6bb213b74abc5a2c5683b0d48022cc30ba77e55db7cc47f59ba99886737605c83. shasum256(Linux)
sha256sum /etc/vault/vault_plugins/venafi-pki-backend
6bb213b74abc5a2c5683b0d48022cc30ba77e55db7cc47f59ba99886737605c8
4. check existing plugin checksum
vault plugin info secret venafi-pki-backend
